Lego Sonic: The Video Game is a video game based on Lego Sonic.
It would have several playable characters from the Sonic series. You could also make your own characters.
The levels would be based on various random things, like Angel Island, and games, like Sonic Unleashed.
The hub would be Space Colony ARK.
The music would be from many games, including the point tally theme, the theme from Scrap Brain Zone.

Some characters, like Knuckles and Tikal, can use Chaos powers in certain cases, much like the Force from Lego Star wars. For example, Chaos Control can teleport the player short distances, and Chaos Spear can be used as an attack and a way to break certain walls.
Some characters, like Sonic and Shadow, can run faster in Run Zones, the beginning and end of which is marked by a blue checkered platform. While in a Run zone, the player will be able to run much faster and be given an exclusive attack.
Tails can access machines that others cannot.
Some characters, like Tails and Cream, can glide over short distances.
Eggman's robots can access doors and mechanisms that others cannot.
Obviously like all LEGO games, characters can use attacks other than this(punches and kicks)
