So you are saying this isn't 2d?Hmm... I got nothing.
there was this one 2D RTS game with a flag builder, lazer tanks etc...
There was this old game for the Dreamcast I remember playing years ago. It was a 3D fighter game, Japanese I think. The stage would constantly be moving forward (relatively). If you got these gems that appeared on the stage, you could go into this super form and cause a lot of damage. It had a "story" mode of sorts.
