My favourites (it's too hard to pick one!):
- duel (occasionally with arena) on the map panic
- m-a-j-r (multi, arena, jetpack, return) capture-the-flag on the map depot
- bomber-ball (maybe with onslaught to jazz things up) on the map futuresport
- Most things multi capture-the-flag or multi-return capture-the-flag-related on the map deadsimple (not that great without multi)
- Still waiting for the perfect king map that doesn't cause a clusterfuck
. Maybe flags can move around during the game, like in *cough*Halo*cough*?
