Welcome back, Teukros! We never did come to a conclusion about that, did we? I've boosted speed and maneuverability across the board to both speed up the games and give a direct relationship between their Rebellion speeds and those given in XWA. Then again, I've made a LOT of other changes, as well. As for my building preferences, as the Rebels I tend to concentrate on the Core with my diplomats, leaving one or two to do the dirty work in the Rim. I try to quickly explore the Rim with Med. Transports and Longprobes, landing troops on the best systems of a sector and then ordering the delivery of a construction yard to the area. It's a slow process, but there's usually little Imperial interferance. This allows me to concentrate my more combat-oriented ships in the Core. I've had success against the computer and against a human player by sticking with 'sector fleets'. Usually nothing more than a (damned) corvette or two at the beginning, they allow for the quick-strike/blockade strategy that so annoys the Empire. I add vessels to the fleet as I'm able, concentrating on the fleets that see more action. I've also learned that even if I'm drastically outnumbered and flight is really the only option, to go ahead and play the battle and retreat to avoid losses.
