My friends and I had a 3 player game this weekend and it was seriously super fun. It ended up being the first thing I ever added to Mission Control. Its called Trade Wars if you want to look it up.
Basically we had a space station in the middle and the object is to pick up cargo and deliver it to your own deployment zone, the player with the most cargo at the end of 10 rounds is the winner.
The balancing effect was really that people were less concerned with the threats on the board and more concerned with how to either stop someone who got cargo and is leaving for his deployment zone or how to get cargo themselves. It got crowded, the game was extremely close and it came down to the last round.
It was really fun.
