A good but cheesy sequil.
You just do the same old thing then the other Roller Coaster Tycoons. Except for that you can do the objectives at anytime (except for some of them), then It is in 3D, and there is an awesome mode called Sandbox Mode. Sandbox Mode is when you can build anything, for you have unlimited money. The way that I look at it is that this is a good but boring game.
The game as good stuff but they just aren't the same as the first couple of games. So that is why I don't like this one that much as the others in the same category.
So that is why I give RCT3: 8.5 out of 10
