Fax and I have logged a lot of 1 on 1 time. You can go up to 4v4, on the maps that support those sized skirmishes. One night, Palooka joined us and we played 2v2 with a computer player in the 4th slot. You can customize the CPU opponent's skill level, so once we tweaked that to the right place, we had a fantastic knock-down drag-out that was a real classic.
