I know I read this one, but I completely missed my own name in it:
A coworker recently shared a game called Chain Reaction with me that I think would translate well into XNA. Better yet, the graphics are easy to build from scratch, which tends to be one big reason I abandon projects. I’m not even a shred of an artist or digital music producer (I can lay tracks, but they aren’t good), so there is a lack of content there that makes indie dev difficult for me. I might give this game a go and see how it turns out.
