2D sprite art would definately be helpfull. I am somewhat self educated in game programming. I am currently converting a P&P strategy game into a 2D, top down PC game. The game is freely available online in PDF form: Zombie Plague. I've got the zombies moving around and breaking things along with some implementation of rules and lots of other little things. Next I'm going to start working on the humans, which I have a better idea how to do after working out the much simpler zombies. You can download what I've done so far here:
Zombie Plague.zip Let me know if you are interested in contributing in any way. I think the 2D art/animation would be most helpfull at this time. If you're interested, I have more details. Once I am done with ZP, I have some more elaborate games I'd like to make- RPG's. I could probably use some design help with them also.
