What's the game that made you say "Hey, this is fun. I wan't more." For me, it's the original Diablo. I played other games before but I played them rather casually, with no real motivation to finish the game. But after Diablo, for almost every game that I play, if it has a single player campaign, I play to the finish. So what's the game that got you started in the wonderful world of gaming? What lured you to the dark side?
