Programming would take a long time to learn. Trust me, I'm starting down that road myself right now. 3d art is also something that takes a lot of time to perfect and requires learning new software.
XML is not as difficult as it may sound, there is not much to learn. It is basically editing text files. Our friend sandman730 is close to being an expert already, he has already added the Merkava to our mod successfully! I'll say that he is a faster learner than I am, it took me a couple days before I really got the hang of it. Joecoolyo I know you could get the hang of it quickly as well, and hopefully you'd enjoy doing it.
This is the area myself, NikNaks, Sheep21, Firestorm94, Bahmo, and now sandman730 are all focusing on at the moment, because it is what stands in our way right now. There really isn't much else left to do, aside from the map. We have to get all the XML finished before we can move forward, and we want to start testing as soon as possible. Art can always be added later, if would be nice if we could all combine on that after we get the XML complete. But we have enough art to have a good, playable mod already.
If you want to give this a try, maybe talk to sandman730 and see what he has to say. You can contact me on yahoo IM, or here via PM, if you'd like me to help you get started. sandman is starting on the unique units, maybe you'd like to try to get a couple of your unique buildings added.
