AlexY: Just because you suck at platforming or are silly enough to play with a keyboard does not make Psychonauts a bad game.
Psychonauts is a pretty good platformer, with lots of areas to explore and lots of stuff to collect - some of the secrets are very creative and memorable.
Also, saying a platformer shouldn't be a collect-a-thon is such a contradiction. Platformers are all about collecting 100 of this or that, because you know there's that one item you just seemingly can't reach at first, yet it only takes a few dedicated hours of practicing jumps. And it's satisfaction when you do reach it. Psychonauts does that and more quite well.
I'll never forget when I accidentally landed on
that balcony in Agent Mia's Disco and entered the chest.
I agree, I played the game with a mouse and keyboard and I didn't have any problems with the controls. In fact I loved the game play. It felt fun the explore and I like using my abilities to explore new places. I never had any difficulties with the game play other then my own mistakes. I liked every bit of the game.
I do disagree with the idea that every platformer has to be a collect-o-thon. Megaman games are not collect-o-thons yet then still have fun game play.
