One year ago I got RCT3 for Christmas, although it was fun at first, but it quickly wore off because of glitches and terrible A.I. When I heard that they were going to make an expansion pack that would not only fix the problems I was having but also allow you to build water parks I was very exicited. So when I got it I was overwhelmed by how much fun it was. It was pretty fun when you could actually finish the missions and the waterparks were awesome, they were what RCT has been missing all these years. Now I can actually stand to play for more than an hour at a time. If you are a fan of strategy or simulation games this is for you.
