I've put thousands of hours into this game since I was about three and to this day I cannot find a simulator that can entrance me half as much. Something about the way the scenarios are designed, the simplicity of the ride builder, the gorgeous spritework and digitized 3D models, plus every other little facet of this game enamors me in a way very, VERY few games ever have. After all these years I finally beat every scenario and I can finally say I've fully mastered this game.
