Classic Sonic games = HOLD RIGHT TO WIN!
3D Classic Sonic games = HOLD UP TO WIN! ( Sonic 3D Blast may be an case for that too since it's in " 2.5D " that looked like it'd be 3D enough. The Special Stage version that is however fully 3D in Sega Saturn Version. )
3D Modern Sonic Games ( Mostly Dreamcast era ) = HOLD UP TO WIN!
Modern Sonic games = BOOST TO WIN!
Sonic Lost World = Er...Parkour to win?
Anyways, I think I might like Sonic Lost World...Also, the whole summary of every Sonic game: UP AND DOWN AND ALL AROUND!
Anywho...Most of us needs Tails, Knuckles & Amy to be playable. I dunno. Maybe from a huge fan demand? But if Tails was an bonus unlockable, he'd break the game so easily just like he did in every Sonic game he appeared in because he can fly. Amy should be alright. Knuckles is er...Fine too?
A Blue Hedgehog who runs at the speed of sound...
A genderless Nightmaren who flies in Nightopia...
A Shooting Star who flies around the Valdi System...
A human boy who uses his legendary chicken suit...
A Rudie skater who sprays Graffiti around the city...
Together...They'll be unstoppable...
