But the art turned out so far is quite impressive, especially for a tile-based game. As some of the main plot aspects are designed to be surprises, you are better off not really knowing. It's not a big secret or anything, it's just that it would be a shame if it were spoiled for you. Wait and see or join the project to help work on it. No one who wanted to help has ever been turned down.
Artistic talent is a real big plus here.
Sorry, there's no money in it for you, but there's plenty of good karma and friendly faces to go around. If you want to simply contribute ideas, all you need is access to e-mail. If you want to playtest, help write code, or do art, you will also need an IBM-compatible PC and network access to the FTP site and website. No matter what you want to do, everyone on the team will appreciate a cooperative spirit. They're not very stringent requirements, as you can see.
