If you had the knowledge and the tools to make Hombrew games for Dreamcast, what would you make. (You can even think of porting/modifying an existing game)

For me, I would like to make a series of Kinnikuman wrestling games, I am not sure if it would be 16-bit 2D or basic Dreamcast style 3D, either way it would play much like Galactic Wrestling for the PS2, just simplified.
