Goodbye weekend/life..

[edit]

So I played it most of the weekend (singleplayer) and decided :

1) The game is laggy as hell, even with most of the settings on low the game grinds to a hault everytime I have a production to choose or something similar. Yes my pc is a few years old, but It still players most new games rather well still.

2) Missing textures? nearing the end of my 2nd game (I was 6hrs+ into it) I started to notice a few missing textures..

3) Bug's, every now and then when I clicked buttons they did nothing.

4) I suck at this game big time. First game I lost was because I got owned by all the other civ's at the same time.. 2nd game I won rather easily. 3rd game I upped the skill level and my civ was unhappy/broke and it seemed impossible to get out of, I guess my management skills let me down some where. So I saved and quit.

5) Why are my games lasting +6 hours? even on quick.

6) Gimme tips : I build lots of cities and make sure I own lots of land/miles etc, build army, take over nearest civ to expand.. Am I doing this right? Can you build armies faster with only a few cities rather than many? What's the best way to expand your borders?
