So do I

Aside from a couple of camera/control issues, I agree wholeheartedly. Work of art.

Small camera issues, as with all 3rd person games. But the game itself is as epic as commander keen. You just want to keep playing. From the luscious graphics to the changing gameplay it keeps you wanting more. I would say this is one of the top 10 games I've played of all time. I see no fault besides the game starting out in a lower resolution than my normal rez! hehe

I'd say go with "Beyond Good and Evil" That one's less Platform[y] and more Action adventure[y]/ Stealth[y]. :D
I'm currently downloading Psychonauts for the first time ever, but all my friends have compared the games' story and characters to Beyond good and evil countless times. I can totally recommend that game to anyone on any day. Just be warned my Direct2Drive version had a few graphical glitches dealing with the volumetric fog and it slowing down my frame rate considerably. Dunno if the GoG version has that issue or not. ^^
