Graphics are best in the genre, if you like theme park sims pick it up for cheap!
The ability this game gives you to put your own creativity into it is cool. Making your own rollercoasters and then going on the coaster cam is also fun. Just that can keep you occupied for hours. There are A LOT of different options for rides to, so don't think you'll run out in a short time.
The Career Mode is somewhat challenging especially to noobeys. You have to kind of get a feel for it before i would start the career mode. Just go into the tutorial and learn the tools and what not. After you find yourself making coasters with a little less trouble than i would suggest starting the career mode to have some more fun with the game.
If you are the same as me this game will grow on you and doesnt get boring as fast as you might of thought. It's defintiely worth its small price tag because i have just as much fun with this 20 dollar game as i do with 60 dollar games.
