I actually have alot of ideas for a RTS but I thought thats what tribal warfare was.
MY ideas was that you don't have direct control over troops. There is a queen alien, which can create babies. There are different classes of babies such as foragers, tree gatherers, hunters, etc. Foragers bring food back for everyone, tree gatheres chop trees so you can build nests etc. I was actually going to start it but I didn't want to copy Idiota's mod. Since you don't have direct control over the units, you would indicate when you wanted to attack, and all your hunters would charge. This way enemy AI could just be once a tribe gets to a certain number, the computer AI starts an attack.
I think it would work similarly to SimAnt, were you could only control one ant at a time.
I do actually wish to start this project, but I'm leaving for uni on saturday and may not have a pc for a month or so.
