My idea is a game called "Sonic Revival" it will be a 3D momentum-based platformer that will have expansive levels. I have 9 levels,Purple Jungle zone,Marble Factory Zone,Pinball Playground Zone,Fiery lake Zone,Space Kingdom Zone,Nuclear Hill Zone,Secret Castle Zone,Dusty Tundra Zone, and Rotten Egg Tower Zone. The playable characters include Sonic(Adventure gameplay),Tails(shooter gameplay),Knuckles(Beat em up platforming),Shadow(Platforming with extra gadgets and vehicles),Silver(slow puzzle platformer near identical to 06),Blaze(boost gameplay). All 6 characters will have one act and one boss per level. The story is that a monster in space has been enslaved by robotnik, it has the ability to change dimensions. The characters team up to use the chaos emeralds to free the monster and return to the original dimension before it's timeline is forgotten from reality and disappears forever. The special stages are unlocked by collecting different numbers of red rings from all stages. After losing a special stage instead of it allowing you to restart or disappearing forever it will make you wait 7 minutes for it to reload. The special stages are simple,fast, and difficult 3d platforming tube where the objective is to collect rings to keep up time and to NOT fall in the pits(it will play kind of like Run). Collecting all chaos emeralds unlocks the super version of every character, the avatar character( a customizable skin for Sonic), and the final boss fight where all 6 characters turn super and team up against the monster. The game will have a mission system like forces. S rank is only obtainable by collecting all 3 blue orbs and getting an A rank in one run. Would be full price($60).
DLC: There will be a dlc for Amy,Mighty, and Ray as playable characters and a dlc to play a 2.5d version of all 9 stages as classic sonic.(all 4 for $5 each)
