Think about it. Maybe four people on a team. You move out to capture nodes, nodes provide Build Points over time. If your ship get kablooied, you buy a new ship that costs Build Points. Something similar to UT2004's Onslaught mode so that you can't just rush their home base without pushing them back, and bam, you've got a game.
Would this be awesome or what?
Man, I've got too many small fun game ideas stacked up in front of me. Sigh.
