one thing i don't like about civ3 is that your bombers can't finish guys off, and you can only attack one unit at a time. this means that taking over a city requires a lot of your units at a time, to weaken the enemy with bombs or artillery, and also to fight each defender. So for a city that has let's say 4 defending troops, you're gonna need 4 or more of your guys, cuz after every round they just keep buying new troops if you don't take over that city. that's gh3y.
in civ2, what was cool was that you were able to completely overwhelm a technologically weak civilization in a bliztkrieg type attack with a few of your dudes. but now, even when your troops are significantly more powerful, you need a lot of planning and positioning to pull off a devastating attack. i guess that makes for a more realistic game, but it's also a real pain in the ass when you've got 30 bombers trying to weaken their stupid warriors or pikemen.
i guess it's because i like to end my wars in just a few rounds... kind of like recent US trends in warfare eh? gotta do that quick before the citizens start bitching about "give peace a chance". What's really sneaky is to agree to a free movement in other people's territory thingy, position all your dudes around all the enemy's cities... then declare war and destroy that civ in one or two rounds. hahaha yes, that is teh r0x!
