This is an oldie, but a goodie - and is currently available through the Humble Bundle store for $0.99. I finally played Psychonauts myself a couple of years ago when it became available on the PSN, having heard from many friends that it was fantastic. I had the most fun I've had with a 3D platformer since Mario 64. If you haven't played it before, now is a great time to nab it. Long before Inception this game had you exploring inside the minds of a host of characters, with a bunch of fun mechanics, and an overwhelming desire to collect all the things. It's one of Double Fine's best. Any other fans out there?
