If you have $10 sitting in your pocket, drive to the store and buy this.
This light-hearted, easy to play game is more fun that you initially might think. Pretty much all you do is lay out tracks, build rides and services for your people, and hire a few people, but fine-tuning every aspect of your park is alot of fun.
Let's get the obligatory graphics and sound out of the way first. I'm pretty sure the graphics are exactly the same as RCT 1, maybe there's some higher resolutions, but it's nothing to leave RCT 1 over. The sound: there are dozens of songs you can have playing, the sound of screaming from rollercoasters, the pops from balloons, quacks from ducks, exclaimations from your guests, a symphony of amusement park sounds constantly pouring from your speakers.
Gameplay is fine. There are several missions you can do including running your own Six Flags park or building in some difficult place such as a castle. I don't really have any complaints about the gameplay, everything you do affects the economy, you can't whine and say that the game is cheating you. Combing through financial records and cutting some fat, such as a particular food stand that no one likes, will help you if you aren't chugging smoothly along, and you can of course take out loans, as long as you keep an eye on the interest payments.
So there you go, my shining review of this awesome Chris Sawyer game. Remember Transport Tycoon? He made that, he made this too! You know this comes from a good place, so peel yourself from your computer chair and go buy this game. Unless your computer is a decade old, you can run this. Your mother will be happy to see you providing cotton candy to five-year-olds instead of pumping lead into a thirty-foot alien.
