okay.
almost through my first game, and I have to say: too many buildings, too many wonders.
A seperate grocery? pleeease...
Battleships are useless, airplanes are more useful than in civ 3, but still not close to what they used to be, artillery got better...
and tanks...seriously, what's that 28 power rating good for, if the damn thing can't take out one set of cavalry...
the promotion system is useless, too much micromanagement.
stacking units and moving stacks is good. sleep/fortify to heal is nice too. Macemen taking out my helicopter gunship is not.
leaders are a bit annoying, but done well enough. religion is...strange.. taxation is stranger. somehow I could play through the game with 0 or 10% tax, for most of the time, and make money, without extorting my neighbours. strange new formula. They took away the palace

The intro is cool. Only if you've played the original civ.
more later.
