Hey, atleast on the 3DS version of Sonic Generations it had online multiplayer mode. If you guys already checked the very first version of this same thread, you know what my ideas for a new Sonic game is already. I'm also thinking of making my ideas more Sonic CD like.
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...
