I liked it, but I finished it in one afternoon. I didn't like that you were so limited on space and most of your park is decoration. There's not a lot of room for actual park improvement. I think it was only around six rollercoasters per park? Something like that. It also took forever to get from one section of your park to the other. It wasn't awful, but it wasn't good either.
I loved the game because it had extreme roller coasters. I also liked it because you could be your own manager with a name and identity. My favorite part was the Wild West trampolines. The hard part is that I could never figure out how to land a roller coaster, but besides that, it was great.
