Alright, here is a topic that I rarely ever see come up but I think will be very interesting to talk about. Most discussion pertaining to Smash Bros. pertains to the content (current and prospective) in regards to the roster. However, Smash Bros. is more than just the roster, much more. There is a lot of content out there in the games, that while not part of the roster, can still absolutely make fans of the the character or game smile.
Assist Trophies, Mii Costumes, Songs, Stages, Spirits/Trophies/Stickers. There are lots of ways for something/someone to be included in Smash Bros. However, we rarely ever hear about being glad something was included in a form outside of the roster. I think this could be a very interesting topic as I am sure there are quite a few things we like that we are personally glad got a nod at all.
I will start off, by giving examples throughout the Smash Bros. series of things that I personally greatly appreciated in terms of content that were outside the roster of their respective games.
Smash 64:
For the original installment, it was novel just seeing all of Nintendo's biggest icons together in a single game. Its roster only had 12 fighters, and 9 selectable stages. However, there was still a few bits of content that gave out non-playable content to some critical major characters from some of the major franchises represented in Smash 64. Most of these were Pokemon (Pokeball Pokemon, the stage hazard Pokemon in Saffron City, the background Pokemon in Saffron City, and the ones appearing in Pikachu's ending screen), but a few other titles got enemies or notable characters from their franchises to have shoutouts. EarthBound/Mother had the most profound with the rest of the playable cast to Mother 2/EarthBound appearing in Ness's ending screen along with two members of the Runaway Five, Mr. Saturn, Frankystein, and Octobot.
However, most of the shoutouts were limited to background appearances to the nine selectable stages. These were usually of generic enemies (Koopa Troopas, Buzzy Beetle, Piranha Plant as a stage hazard, Lakitu, Shy Guys, Kirby's Bronto Burt, and DKC's Necky), but two series critical characters also received a shoutout through this method. They were King Dedede and Ridley.
For the latter, I remember being absolutely ecstatic seeing that Ridley had made a cameo in what was becoming one of my favorite games for the Nintendo 64. I had long hoped for a Metroid game for the Nintendo 64, and Samus being a part on the Smash roster was an incredible miracle to me especially when the series was dormant at the time for five years and there was no announcements at all about a new game in the series being in development. Samus and Ridley being my two favorite things from the Metroid series, it was nice to see both of them have some sort of appearance in Smash Bros. I would literally just play and pause on Planet Zebes as Samus and daydream that it was a new Metroid title.
It was also seeing Ridley in the background to Smash 64 that got me to daydream about the possibility of him someday becoming a fighter in Smash Bros. There was actually a part of me that thought the next title in the series would involve adding the main antagonist/rival for each of the franchises represented in Smash Bros., since the most obvious additions for many of them seemed to be villains/rivals such as Bowser, Ganondorf, King Dedede, Wolf, etc. However, I considered it miraculous enough that Samus managed to make it onto the roster of 12, and that if her slot could have easily gone to Wario (of which three Wario Land games had already been released by the time Smash 64 was made).
Ridley's cameo in Smash 64 was the sprinkles to the masterpiece cake (well at the time it was to me) that was Smash 64. Not a necessary part of the game/cake, but definitely something that made it stand out more to me personally.
Melee:
As I said in a previous post, Melee massively expanded upon everything that made Smash 64 great. Moreover, it actually seemed to celebrate Nintendo as whole. Melee is probably the only game in the Smash Bros. series where I actually enjoyed collecting and viewing the trophies because it gave a 3D model to many characters who at the time did not have one. Melee was the first time seeing characters like Ridley, Dixie Kong, Pit, Meta Knight, and many others in 3D, and having freedom to view the model from different angles and lighting. This was a big deal for many Nintendo fans that had grown up with a NES/SNES and were disappointed that many of their favorite characters did not make the jump to 3D with the Nintendo 64.
The trophy system in Melee was something I enjoyed than most of the new additions to the roster. I now had a game where almost all of my favorite Nintendo characters were now given a reference in a single title. On that note, I do want say I actually remember being a bit disappointed when the trophy list came out and there was two absences that seemed peculiar to me. One which was Diddy Kong, which was very bizarre considering how both Dixie Kong and K. Rool received trophies, and Diddy Kong himself being one of the most highly requested newcomers for Melee. Even to this day, people remark how bizarre that absence was. The other was the Pico not being a part of F-Zero's trophies. All of the classic pilots except him (Captain Falcon, Samurai Goroh, Dr. Stewart) had been given trophies (along with Jody Summer who was given the most focus of all the new pilots F-Zero X introduced), but Pico somehow did not get one. I was probably one of the few disappointed on this though.
However aside from that minor quibble, the rest of the trophy selection was absolutely incredible. I was extremely thankful to have a virtual museum for all of my favorite Nintendo franchises, and to see several of my favorite characters in 3D for the first time. The Ridley model in particular was something I spent a lot of time viewing. The level of detail attached to it, made me think at the time that perhaps Ridley was considered for a fighter, but they simply did not have the time nor did he have the priority (the likes of Wario, Diddy Kong, and King Dedede had not been added either). I daydreamed not just about Ridley being a fighter in Smash Bros., but also the day a 3D Metroid game finally would be made, and the trophies for Ridley, Metroid, and Kraid definitely wet my appetite for the upcoming GameCube title.
On that last one, aside from the trophy system, the other non-playable role surprise for me was Brinstar Depths. It actually was one of the things I was most hyped about in regards to Melee's hidden content. It was really nice to have a stage literally and figuratively revolve around one of Metroid's most iconic bosses. It also captured the moody atmospheric feel of the Metroid series that I did not think Planet Zebes or Brinstar had (a lot of this was thanks to Brinstar Depth's lighting and music track). Being able to see Kraid in 3D for the first time was really hype inducing. Funny enough, this ended up being his only 3D appearance.
Brawl:
Nothing in particular stood out from Brawl to me in terms of non-playable content, aside from liking that a lot of of the new stages borrowing more closely to particular titles in their respective series. I did like they Norfair was brought in as a location, as that was Ridley's stomping grounds in several titles to the Metroid series, and at the time it was confirmed it actually gave me hope Ridley would be playable in that title.
I did like that Brawl did include Pico as a trophy, but in general, I did not enjoy the trophy system as much as I did for Melee for two reasons. One is that the novelty of seeing many characters in 3D for the first time wore off, and secondly was that most of the trophies seemed to be direct model rips from particular GameCube and Wii titles.
I did not care much for the sticker system either, and I was disappointed you could not zoom in on them, or view them individually.
I did really like the massive song selection in Brawl. It was absolutely massive, I was surprised by just how much was included.
Smash 4 3DS:
As I have said a few times before, I never owned Smash 4 Wii U since I never owned a Wii U. However, there are two things from Smash 3DS that really made me smile in terms of non-roster content.
One was the inclusion of a stage based off of Balloon Fight. Balloon Fight is probably my favorite early NES title (titles released prior to Super Mario Bros.), and in general such a fun and underrated game. A part of me was hoping it would someday get some sort of major notice in Smash Bros. (the most conventional belief would be through a fighter since Ice Climbers, Pit, and ROB were all added). However, as a fan of Balloon Fight, I can say I am extremely happy with simply a stage representing this fun little title. It receiving a stage was one of the biggest pleasant surprises to me in regards to Smash 4 in general, and I was quite happy to see it in 3DS version to Smash 4 (which was the only version I ever got since I only owned a 3DS).
In general, I really liked the stage selection for a lot of the Smash 4 3DS stages. Gerudo Valley was something I had suggested as an idea back even before Brawl's announcement (though its implementation was a lot different than what I had in mind). Other standouts to me was the stage based of the SNES F-Zero and Magicant. I also felt Rainbow Road was the most fitting stage to represent the Mario Kart franchise as a whole (its peculiar why it did not come back for Ultimate).
Aside from stages, I really liked roster of Smash Run enemies. I was really happy they actually went with enemies from various Nintendo franchises instead of more of the bizarre kind of enemies found in the Subspace Emissary. It was a really nice selection and many of Nintendo's franchises got a nice shoutout.
Ultimate:
As I said before, personally, I liked the spirit system as it gives almost every single significant or notable thing from all of Nintendo's franchises some sort of shoutout. Leif from Fire Emblem (the only piece of Thracia 776 content in Ultimate, FE5 is actually the only FE title that is not a remake not to have any sort of song in Ultimate) , getting a spirit battle was really nice, as that is one of my favorite games in the whole series and Leif one of my favorite lords. In general, I was really surprised how comprehensive the list of spirits is, and there are very few notable absences in general.
I was happy that a remix of Lower Norfair finally ended up being part of the track list for the Metroid series (and just in time for Ridley's playable debut). In general, I really loved many of the remixes made for the Castlevania and Mega Man series (Cross Your Heart and Snake Man in particular are breathtaking). The music selection amazed me even more than Brawl's, and that is saying something.
The new Mii Costumes were another thing that was pleasantly surprised about. I really liked how many of Nintendo's minor franchises (Panel de Pon, Golden Sun, Chibi Robo, Custom Robo), many of which have been on hiatus for a long time, got a nice consolation prize shoutout in the form of Mii costumes of their series' icons. While those series going into hiatus meant they probably would not have been up for roster consideration even if the base game had more newcomer slots available, it was really nice of Sakurai and his team to acknowledge that those series are a part of Nintendo history and give them some sort of playable status in the game even if its Mii's role-playing as them.
Perhaps the biggest pleasant surprise for me though was something that I was probably the only person to feel quite a bit of hype in regards to its inclusion. A distant hope of mine in regards to Smash Bros. was that Pico would get some sort of notable role in Smash Bros. beyond being a trophy/spirit/sticker. However, with F-Zero being in hiatus for well over a decade, and Pico having non-existent popularity, I strongly doubted it would ever happen.
I never could have imagined outright sort of controlling him within Smash Bros. Using his spirit to activate the Wild Goose, was something that made Ultimate even more special to me, and was one of the stand out moments for me personally when playing through World of Light. It easily could have been Jody Summer (who was a trophy in Melee over him) or any other of the F-Zero characters included as spirits, but it somehow ended up being Pico. I never ever could have imagined controlling the Wild Goose in a Smash Bros. title, and this easily made up for disappointment I had with the him not having a trophy in Melee several times over.
Many characters will never have the "credentials" or right situation to make the roster, and I understood that for Pico, however, I still wanted something for a character whom was my personal favorite for one of my favorite Nintendo franchises. Pico's role in the World of Light may not have been on the level of an Assist Trophy or Mii Costume role, but it was still something that fulfilled what I was hoping for but thought most likely would never happen.
Closing thoughts:
As can be seen, while the roster is often what most discussion and speculation for Smash Bros. is driven for, there is still a lot of content that is outside of the roster that can also please fans of those particular games and characters. With Smash 64 it began with Ridley's background cameo, and now with Ultimate it is cruising in the Wild Goose. Some of the widest smiles I had in regards to Smash content were small touches like that to which I was not expecting at all.
For some of us, there are characters and games we love that simply will never make the roster (they either are too obscure and/or have little popularity), so seeing a notable sort of acknowledgement for them is just as pleasing as a personal favorite getting a spot on the roster.
I am not sure if anyone else has also experienced something similar to me where they were massively pleased with some sort of non-roster content, but I would like to hear from others on this topic as I am sure there at least a few others that have had similar experiences, and I am curious to see whom their "Pico's" are.
Thank you for your time in reading this short piece. I hope those that bothered to read it got at least a little enjoyment or amusement out of it.
