I like to go with one capital ship at the start, I play the Colonials, usually the Galactica, although I have tried the Mercury and the Sentrus recently and level it up to at least 6 or 7. I go for all of the weapon and the health upgrades, getting the most health for each Battlestar to counter the cylons ability to pump out about 4 or 5 basestars in the first 5 minutes. Don't go with any support cruisers, apart from maybe the Enterprise or percheron model. If you really can't counter the cylons, pump out Mercury class Battlestars and get the ram ability and just take out hight level cylon capital ships.
It has to be the best mod ever and I never play normal sisn anymore. I really do like just getting one Galactica class and just leave my home to settle for a new home on the other side of the map (Earth). Yes I am obsessed with the series'. Good idea to get the Galactica map pack (3 maps) containing Earth, Kobol, Caprica and the 12 tribes of Kobol in one map. Well worth it.
