The original galactica board game is a big hit in our gaming group, so we were looking forward to Pegasus. Overall, we like the new characters and the ability to play a cylon with various victory conditions was good too, but the New Caprica section, we felt, added nothing to the game.
The problem stems from choice, as the cylon, you basically throw either crisis cards or occupation forces at the humans, but with occ forces being killed on a 6+, it's quite easy for the humans to keep them under control, a couple of XO's or Strategic Plannings make life very easy indeed. This makes this section really, really dull as the cylon player, and as the human you basically sit on the location for prepping the civilian ships.
Overall, 3/5 is fair for this expansion, don't buy it unless all you're after are a few new options for your base game, cos it doesn't offer much.
