This game is awesome. That should be pointed out straight away.
Did you like Monkey Island(s) and are sad games as good are not made any more? Do you hate it when you buy a game and the story makes you feel your 8yr son could write better? Or that what all that hype wasn't telling you was that the game is riddled with bugs?
Forget all that, Psychonauts answers all those problems. The story is engaging, the storyline is intriguing and executed with near perfection, the concept of the game feels fresh and interesting and I can't in any honesty mock the gameplay mechanics. Only a slight minus for sounds: The music is fitting and enhances the mood greatly and the sound effects are by no mean bad, but sometimes you just get the feel that they gave only 90% instead of the 110% they gave for everything else; sometimes it's the actual quality of the soundtrack, sometimes the voices fail to fit the character perfectly. But don't get me wrong, that's mostly nitpicking. Honestly.
This game will most likely be the best game of the year and yet stay as one of the most unnotable. A shame that, because this is the long-awaited game that goes the extra mile from good to excellent. Unless you're a die-hard FPS-only fan or honestly think that World of Warcraft is the end-all be-all game, try out this gem in the rough. You won't be disappointed.
