Any of the Sim City games.While you might be complaining about how dumb it is,you'll look up and notice that you've been playing for hours.
The first and second Tony Hawk games are the most addictive that I've ever played.They completely changed my sleeping patters while I was playing them.I would wake up early on weekends and end up playing until midday without going to the bathroom or getting anything to eat.
Plus,everything that I saw on the street in the real world,I thought about how I could skate it in the video game.
