Battlestar Galactica is the best board game ever made. I usually play it once a week, more if possible. We almost always have a great time accusing each other of being a Cylon and secretly trying to make the humans lose.
What is even better than Battlestar Galactica the board game? the EXPANSION to Battlestar Galactica the board game of course! Looking forward to getting this game at Essen Speil this year (will be going to the game fair again this year!)
If you are a fan of the show then I really recommend this game, it is best with 5 players, but can be played with 3-6. It really captures the show well and the expansion looks to capture the theme of the later seasons aswell.
