Capcom's been making a lot of collections of their series lately, so I hope they do one for Final Fight or the 3D Fighting games. Obviously, I can't get to them all, but if they slowly work on all of those, it'd be great.
I'm not sure what I want to see outta Nintendo outside of Metroid Prime 4, at least out of the things that are feasible.
I DO want a Soul Calibur 2 port with Link, Heihachi and Spawn all on the same version. Mods have gotten close to getting that perfect version of the game at least. Some other extra features like a color edit mode, some of the Weapon Master exclusive stages and rollback netcode would be awesome too. Everything else could just be the console version's extra stuff and the game's basically perfect as it is.
