I seriously cannot understand how anyone can find anything salvagable in Sonic 06 (other than the music of course), that being said there is a game that I can apply the "revolutionary on paper" mentality to:
Bubsy 3D is actually a tragic miracle of game development. It started production a year after Mario 64 did with no reference as to what that game (or others like Croc or Crash Bandicoot) looked like. Despite being created with an 11-or-so person team and no other 3D platformers as a guide except maybe Jumping Flash, Bubsy 3D actually is a rather sophisticated 3D platformer for its time and dev background, in some cases more so than Crash or Mario 64.
-Power-ups, not featured in either Mario or Crash (discounting Aku Aku crates and the wing/metal caps, the prior being a basic extra hit/invincibility and the latter two being extremely situational)
-Co-op mode similar in nature to what would later be done in Mario Galaxy 2, and arguably conceptually better with the reticle player being able to swap with player 1 by shooting Bubsy, as well as an ammo system.
-The ability to use collectables as projectiles - Pac-Man World did something similar later into the PS1's lifespan but Bubsy did a better job of it IMO given that you have to press a button when close to an atom rather than stockpiling them. Also Pac-Man World had a really strange angle to the throw - but that's irrelevant since Pac-Man World is overall a different type of platformer level layout-wise than Bubsy 3D so the throw angles can't be fairly compaired all things considered.
Bubsy 3D is not a good game in the slightest, but damn it has some great ideas and is an amazing acomplishment given it's development circumstances.
Sony, well, it'd be the only way we can even get their first-parties in Smash, but they'd need to bleed money for them to be bought, and that has yet to happen still.
