My nasty obsession with Civilization - the first one with crappy blocky graphics that randomly froze in the middle of battles - began in high school. I would play several turns where I'd annihilate a rival civilization and then run to class to take my final exams.
Now I play Civilization V, which isn't a great game but as addicting perhaps as World of Warcraft. It can be very cathartic to drop the A-bomb on an annoying rival civilization if you've had a bad day at work. The downside? You've just blown 4 hours playing the game straight. Will this stop me from playing? Hell no! I still need to kick Napoleon's ass.
