Well Jawib, what if there were weapons available, such as rocket launchers, but also things like land mines, and little turrets that you could control (this is what I had in mind anyway for the first person mode...obviously an ak47 won't do crap against a hovertank).
Hmm...It might be ok. Still, I'm thinking it would be pretty easy to blast a little guy running around with your tank (unless there's a lot of spots to find cover).

Maybe you could just make it an option, so you can have varied types of gameplay. For that matter, you might make it an option to have a certain number of spawns per game...I guess its just a matter of how much time you want to spend messing around with ideas...
