Long time lurker and first time poster. I've run sci fi games since I picked up my first copy of Traveller back in 1980. I've always really loved the simplicity and playability of CT's character generation system, personal combat, etc. But I've never liked the 2d universe or the HG warship rules. Personally I've always ditched the Traveller Star Ship rules and replaced them with the ones from FGU's Space Opera. Anyone else ever done anything similar?
