Alright folks, I wanted to keep this as one of the surprises but on second thought I'd rather run it across you all first.
So I'm planning on doing a version of Legacy called Legacy Tournament Edition (or Legacy TE). It would differ from Legacy in three specific ways:
1. No vanilla Project M 3.6 costumes would be touched at all (including being replaced)
2. 10 costumes per character would still happen, but instead of new alts, it would be recolors of the last costume (for example, instead of having helmetless Captain Falcon and Mach Rider Falcon, it would be red and green recolors of Retro Falcon).
3. Character and universal fighting SFX wouldn't be touched (no changed voices for Wario, Luigi, Sonic, DK, Diddy, etc)
Essentially it would still add custom music, alternate stages, and expanded costume slots to the game, but it would be even more friendly for people trying to use this build in a tournament (also filesize would be lower, making it more SD card friendly).
Thoughts?
