Years ago I was introduced to what seemed at the time to be a very boring, tedious computer game. With real time strategy games all the rage, why on earth should I pay attention to a turn based game? It didn't make sense, but people refused to stop talking about it, so I was compelled to at least try it out. Needless to say, I got hooked on the game in a big way.
Yes, I am aware that there is a fourth installment to this game franchise. But that doesn't exist yet for us Mac users, and quite frankly, I'm kinda glad. We finally get the Play the World expansion pack for the Apple OS at the end of the year, so we have lots of gaming goodness to get caught up with before we move to Civ IV.
The only real problem with the game is the amount of time it eats up. I hear that in Civ IV, they have a built in alarm clock so you can be reminded to quit occasionally. I do like that I can play for an hour at a time and slowly work at a game though, which is good since most games take days to complete. It's really too bad I'm not a playtester for this sort of thing - I'd be the most dedicated employee ever.
