Probably one of the best psp games ever released.
Gameplay: 8
The reason i put "only" an eight for gamplay is because all the mini-games there are in the game, you get distracted from what, I guess, was the real point of it all: building your own theme park.
If you've ever played Theme Park World and remember the mini-games, well this game goes far beyond that. You can ride any rollercoaster, design it and even colour it. But this isn't all, you can also play a multitude of other mini-games such as first person shooters, mini-golf, destruction derby-style games with radio commanded cars, and much MUCH more. You pretty much run your park by playing all those mini-games.
Graphics: 10!
This game features without hesitating the most enjoyable graphics for the psp since burnout: legends. There is realy nothing much more to say about this except that you won't be disapointed.
Sound: 9
I can easly say there is not one irritating sound in the whole game. The voice acting for tutorials/missions is ok, just what's needed. Apart from the rollercoaster/merry-go-round noises you'll hear in the background, there is for each part in your park a different "radio" this means that you have a list of more or less 5 songs for each theme coming with the occasional "thrillville is great" from the thrillville radio host(s). You might say this isn't much, but considering you spend about 5-20 minutes in each part you wont be hearing the same music over and over. Also each park has different parts which is alot of songs in the end.
Value:8
It has a great value for a psp game, if you found the previous psp-games to be "ok" you will definitely like this game alot. But if you own a ps2-ps3, you might aswell get a more intresting game.
Finally i would like to say that, if you like a fun, cool game to play for the psp, this is definitely it. But if you're looking for a realy intresting and challanging game you might aswell forget the psp (or go for killzone).
