Since we only seem to get 4 players max (that's what I've seen) I think the capture the flag would be a better game. Me and BAKup spent a game of the Conquest type just chasing after the flags to keep the ticket count up. Not a lot of action there, like a dog chasing it's tail. Capture the flag should be more exciting for the small number of players. You might consider dropping some maps that are for the 32-64 players, since that's a lot of real estate to cover for one or two people on a team...
I'm still trying to figure out which map is my favorite, there are some great sniper spots in the ones with cities in them... But the B-17 just plain rocks!!!
Oh yeah I finally got a submarine and proceeded to run it aground in no time at all
