I've been painting up starships for some time over the past couple of months. Torn between Full Thrust and another rule set. But its a lot of fun!
Most of the fleets are commensurate with Earth politics so you have Russian, German, British etc. with mixed abilities. Full Thrust allows for weapons and ship customisation so more flexible. Fast, fun and with a damage effect system that sees ships degrade in combat (or simply blow up for the smaller ones).
