i came up of a game idea where worlds collide as Nintendo, Sega and other video game idols.

Copy of 6 systems

The playable characters are Mario, Sonic, Shadow, Ty, Sly and Crash. There world gets taking over by there biggest enimes, they send out dark creatures from another demension, It's up to these heroes to save their worlds.

What do you think? what characters do you want to be replaced? post in comments.
