Two Point Death Egg! Two Point Eggman Empire! Manage your Egg Pawns, capture animals to turn into badniks, manage campaigns in taking over zones etc.
Now that's totally a wild idea that I will support.
It could be a prelude to Sonic Forces when in the end Eggman's succeed conquering the world.
Sonic, Knuckles, and Tails already showed up in Two Point Hospital, but as costumes only.
About time the real ones showed up.
