I remember back in Brawl third party characters were welcome additions and seemed really cool. In hindsight though, it may have opened a Pandora’s box.
Brawl had 2 third party characters.
Smash 4 for both the Wii U and 3DS had 7 third party characters (3 of them were DLC).
Ultimate currently has 14 third party characters, including the ones who are echo fighters, and assuming FP5 will probably be another third party character, that will bring the total number up to 15 (with 5 of them being DLC).
It’s alarming for sure because we grew up believing this game is a celebration of Nintendo All-Stars. I don’t want to sound bitter about it though; I find that some of the third party additions are a great fit for Smash such as Sonic, Mega Man, PAC-Man, the Belmonts, and Banjo & Kazooie. Some of the others are debatable, I find Ryu and Ken cool additions and they have had their games on the Super Nintendo.
That said though, it’s still alarming regardless since right now third party characters are becoming nearly 20% of the roster. First party characters to me are what made this game special in the first place, but it looks like first party DLC additions are getting left by the wayside because Nintendo is spending a lot of their energy impressing outside companies. Imagine if Nintendo spent a lot of energy impressing their fans instead, such as the ones who grew up with their characters. If they did, we could get more first party representation along with a better online service and better support for esports events.
There have been debates going on in other forums such as Gamefaqs. Some of them think first party characters are not “hype” enough like third party characters are. I wonder what their positions are now though. I find first party characters really “hype” especially now more than ever because no one is expecting first party characters in the next DLC wave at this point.
