I installed the first four (of 18) disks for the Sims 2 earlier today, and found out something I'd expected; the game is a power hog. It sucks the life out of the battery as fast as a vampire sucks the life out of an innocent victim. I think I won't be playing the game in the park. On the bright side the graphics are very nice and it runs smoothly, so I'm pretty happy about that.
