Non video game fans: Have you played a game that really sucked you in? I can't stop...LOL!?

When my first 2 kids were very small (baby and toddler), my brother gave me his old video game system, a Nintendo 64. I didn't think I'd use it much, but it was winter and the boys napped during the afternoons. Out of boredom, I tried the one game he had included - it was 'Ecco the Dolphin' - and WOW was it addictive. It was really pretty and relaxing - first I had to learn how to "swim" (haha - click buttons, that is) and then there were progressively harder missions. I played it so much that at night, my dreams were about the game!! And all over the living room were scraps of paper with my "codes" for saving/restarting my game. I know there were probably other things I should have been doing, but I remember those afternoons fondly. Have fun with Ratchet and Clank!
