Four captains to play Star Trek: Fleet Captains

We played (in the end of 2011) a very fun game of Star Trek: Fleet Captains with four players. I choose to set the victory point objective to 12 to have a not too long game (with four players it's longer). Eric and me have played the Klingon. Seb & JB were Federation captains.
We were crushed (12 VP against 3)...
