Summary: There is a lot of stuff to do in Thrillville. Minigolf, Go-Karts, shooting arenas, etc. The only problem is none of the stuff is fun to do. Go-karts handle very bad, and the shooting arenas are boring, mainly because they have tricky controls. Designing a roller coaster is a hassle, especially since there too many restrictions. You have to build the ride in a small amount of space, meaning that it'll be a short ride.
Summary: You start off by choosing the character you'd like to play, and then after a short interactive tutorial you're off and running at attempting to manage your own theme park. You are given missions to complete in order to unlock more theme parks. Rides are either premade, which your character can purchase, or can be custom built in build mode. Your character can also ride the rollercoasters.
