I didn't know it's a game, thought it was just a screen saver. Seriously, what else looks gayer than the scrambler on your screen when you and your friends walk into the room.
I tried the game once. The rides were all dipped in a pool of plastic before they were built. Honestly. Although the simulation I should say, it does it's good really well. It just isn't fun though which sucks when you think it would be fantastic.
