I know what I'm making, but I have no experience with making games, with the exception of making logos and directing/producing. I can't just get some images, animation, etc. and have a working game. I need a programmer to make keys do things, make it so you die when you're shot with a rocket launcher, make it so the grenade blows up, etc.

Here, if you can help me figure out whether it'll be flash or not, it would be highly appreciated. It's 3D, NOT a side scroller, online capable (if I can't find good way of doing it I've already got a solution), and able to use custom maps and variants (with a great way, too).
