Yeah Civ I was actually the first game that really got me hooked. Oh those countless wasted hours.. but boy was it fun. Nowadays I only play III and a bit of II, whom require a little different tactics. I usually try to expand as much as possible, then start taking out smaller neigbours one by one, either with steel or try to get them to military alliances. Of course, all sorts of espionage and backstabbing are close to my heart, that way you donīt have to waste resources on that field.
