SSX3 Diablo 2 World of Warcraft, IF it would be available for the rest of my life. I'm still not tired of that game..over seven years after I began playing it. But if WoW wouldn't be available for the rest of my life, then..that's really hard. It would have to be something I can constantly restart and play over and over, or that provides an endless amount of replayability. Perhaps Transport Tycoon.
How I wish we could get a proper, new Transport Tycoon. That damn Locomotion was a mess. --- -War. War never changes. (Fallout) -War. War has changed. (MGS4)
