I just bought this game yesterday and played one full three hour game against as TEC with normal AI (and got my ass handed to me). I imagine this will come naturally over time, but I'm not exactly sure how to spend my resources properly. More specifically how aggresively should I build units and what is considered a good fleet size? 10, 15, 20, 25 ships? Should I always have a surplus of money/metal/crystals on hand in case I need to build up an army rapidly, and if so, how much? I'm asking these questions because I honestly have no idea if there is a unit upkeep cost, or a cost for owning more colonies. I had a nasty habit of going broke playing Civ4 by expanding too much. On the topic of expansion, should I bother colonizing asteroids or should I just move on to planets? One more question, should I just build as many capitol ships as possible or work on leveling up 1-3?
