Anime style drawing and animating (like http://www.dofus.com/)
Illustrator, Photoshop, or something similar
Any programming knowledge a plus
I'm currently developing a real-time multiplayer flash tournament game that needs graphics similar to http://www.dofus.com/
It's going to be based around a website that's going to have pay-for premium items.
It's quite a bit of animation work, but I'm bringing loads of programming work to the table. I'm also a business major, so everything we do will be incorporated into a strategy to make money. We'll find a way to split the profits in a way that is fair. The ultimate goal is to be as successful as http://www.dofus.com/ (though the game will be completely different).
