Sim Themepark is a stupid game. It came after Rct so you know that they mostly copied them. This black dot thing gives you so many hints on the game which is very annoying plus its easy to win scenarios. Rides are impossible to create. I've tried this other coaster program which i found at K-mart for $10. It was terrible you just click on loops and turns and stuff, The graphics were terrible. Also you can download this other coaster creation game by disney at
www.theunderdogs.org Its a very old game i think 1991 or something but you have all these features to make and you can ride the coaster and you can see what critics think about it.
