settlers 4

i enjoyed the settlers 4 so much as it had very good economy building processes, unlike so many stratiegy games. then, with the economy, one can build an army. i find that at first, i was building lots of towers very spread out with one man in them, but later switched to building them in 3's with fully garisoned, level 3 troops. then, i had a "quick reaction army group" to deal with nastys.
i enjoyed playing with the romans the most because i enjoyed how they almost always responed to a command, whereas the mayans kept running off on their own little crusade. the roman medic was far more usful than the blow piper or the axe man, as they allow you to make an army last.

any comments? why did you enjoy playing the most and what was your overall inpression of the game?
