gee, I had forgotten about Galaxies At War, I think I d'loaded it and never installed, have to dig around
One thing non-players need to understand about SFB is that there are many, many rules. And by that I mean, many... There's a lot. There are some to keep things balanced about fleet limits and command-and-control limits, partly because somewhere sometime some players pushed the rules to the limit, and then a rule to officiate future disputes arose. (All this is one of seeveral reasons I'm glad to have moved on to SFC from SFB) So, usually, yes, Bases (BS, BATS, SB) are limited to one PF hangar module. I forget how hard and fast the rules were, but "officially" you could only have 1 PF flotilla (of 6) in a battlegroup of 11 (a game limit); each flotilla counts as 1 unit, so you could have 2 flotillas but only 10 ships. Fighter groups count in there too; it gets complicated. Remember also, that each of these units need to have a form filled out with thier energy plt for each turn. Does your brain hurt yet? One turn (32 impluses, or the time it takes to almost arm a photon fully) with 9-11 ships per side, would take an hour if you were lucky.
I love SFC.
I'm interested in your approach to "more than 4 PF aboard your carrier." I'm working on a ftrlist that has what I call "Figher/Interceptors," or super-heavy fighters in SFB terms. Phaser1s, drone racks, speeds of 25+, damage rating of 25-30, and using the awesome Space: 1999 Hawks Atheorhaven made on Battleclinic.
