I remember being totally addicted to Sonic the Hedgehog and Super Metroid when I was a kid. Later Pilot Wings 64, San Francisco Rush, Goldeneye, and Super Smash Bros had me. Time Splitters and II, Star Wars: Rogue Leader, Halo, Super Mario Sunshine and Double Dash were also quite addictive. I also became hooked on Kingdom Hearts 2 and stayed up for 3 days straight just to finish it. That was strange because I liked the original Kingdom Hearts, but was never addicted to it. The most recent addiction I've had was The Elder Scrolls IV: Oblivion, but not the expansions to it. There are many games I like play, but I haven't been addicted to anything since Oblivion. My taste in games is always evolving and I'm always trying new things, but my attention quickly wanes anymore, so I'm not playing anything for more than 2 hours straight...provided I even have that much time to play.
I agree that it is primarily a boy thing, but I think girls can be addicted also. It's certainly affected by gender programming, but I think personality also contributes to it and you have that kind of personality.
