I'm still exploring the edges of the game so score means nothing to me.
Let's see any of you walk up to an enemy base, dance with the troops in the hanger, climb on top of it, and shoot up the guy who earlier had shot you down as he rearms without being killed by the auto ack.
Let's see you guys drop enemy HQ after flying 45 minutes NOE over hilly terrain and then fly another 45 minutes over the same hilly terrain to successfully land the mission.
It's a challenge and different than the hordemongering, picking, and running that comprises most arena action.
I'll let you know when I decide to concentrate on fighter score.
