Okay, so tinfoil hat time/question:
Does Nintendo give Sakurai a set budget when making Smash Bros, or do they just trickle in money as they go? I'm mainly asking because of how it could relate to Reimu.
Let's have a look-see through the Challenger Packs and the money they may have spent on them throughout the years:
- Piranha Plant
- Free bonus DLC character. $
- Meant to be a part of the base roster after Incineroar, but schedule circumstances changed that. $
- Because of how easy it is to make him and because of how he's a first-party, PP may have cost less money to develop than any other DLC character ever. $
- Joker
- Our first official DLC character. $
- Sakurai loved Persona 5, the game was the main inspiration behind the menu.
- Hero
- Koichi Sugiyama was likely very miserly, was only able to provide MIDI tracks instead of the fully-orchestrated tracks. Even with that, it must've been expensive.
- Has the highest number of distinct Specials of any Smash character thanks to Command Selection. $$$
- Had to hire different voice actors for each of the 4 Heroes.
- Banjo & Kazooie
- Close ties with Nintendo thanks to B-K's history. $
- Microsoft and Nintendo had been getting really chummy at the time. $
- Terry
- SNK was the most generous company out of everyone, beating out Konami prior. $
- Due to Fatal Fury being a 4-button fighter as opposed to Street Fighter's 6-buttons, was generally easier to develop standard attacks for. $
- Comes with GO! mechanic and unique inputs. $$
- KoF Stadium possesses a bajillion stage cameos and has that wall mechanic. $$
- Byleth
- Was rumored to be initially a Monster Hunter rep, but didn't fall through. $$
- Min Min
- Direct request from Yabuki himself. $
- Min Min has a unique control scheme in comparison to the rest of the fighters. $$$
- Steve
- Negotiations took 5 years to develop. Vergeben, love him or hate him, said Minecraft content was coming to Smash long before Steve's reveal. $$$
- Required Sakurai to rewrite every single stage to accommodate Neutral Special. $$$
- Was issued by a co-worker as a challenge for Sakurai. (Could be a joke, could be serious. I don't know) $$
- Sephiroth
- lods of emone probably went to music negotiations since we got 9 songs out of FF with this challenger pack. $$$
- Only speaks Japanese for consistency with Cloud. $
- Northern Cave background seems like a very intricate render, as opposed to other stages like Yggdrasil's Altar and Garreg Mach Monastery. $$$
- Pyra/Mythra
- Was initially going to be a trio character with Rex, but limitations led to the idea being scrapped, turning Pyra and Mythra into a Zelda/Sheik-type character. $$$
- Required contacting Skye Bennett and Al Weaver, British voice actors. $$
- Kazuya
- Sakurai discussed how difficult it would be to put Tekken's movement into Smash when discussing Heihachi. $
- Kazuya has 8 input directions to choose from for his tilts. $$
- Tekken has 39 songs in Smash Bros. $$
What does this have to do with Reimu? Well, Smash has always had some lowkey reveals at the end. If Reimu actually is our final character, then it'd make sense for the final Challenger Pack to require less money, too. There are a metric ton of points in favor of this, too:
ZUN's very lax when it comes to copyrights, as I may have mentioned many a time on this thread, so negotiations could very well be the most affordable out of anyone. $
Team Shanghai Alice is a one-man dev team, most likely meaning not much money was spent on drawing the artwork and composing the songs. $
That "graze" glitch still hasn't been fixed. Sakurai and the dev team could've fixed it when making the Kazuya patch, but it's still there. That could be fixed in a later patch, but as it stands, it's still there. $
Touhou Project makes sense on so many levels as a finale, as not only would it reflect the final DLC character in Smash 4 being Bayonetta with Byleth being like Corrin, but these points, among others I haven't thought of yet, would point it to being Reimu mainly because Sakurai's dev team is approaching the end and probably require fewer resources, much like with Corrin and Bayonetta. Master Chief is heavily rumored as of late, yes, but he sounds really expensive, and as of right now, Smash has put the most money into Microsoft content with not just Banjo-Kazooie and Minecraft, but also Fallout and most recently Skyrim.
TL;DR: Team Shanghai Alice probably requires the least amount of money for negotiations and development than any fighter we've had so far, making her the most likely candidate for our final challenger.
