Wow. That's the most outstanding thing I've ever seen...Sphinx and Cursed Mummy? Beyond good and evil? Damn! Never though I'd hear those game coming out of your mouth...I haven't played either because they look like younger audience games, but maybe I'll look into them.
As for Eternal Darkness, I bought it when it first came out, and it was new and cool for the first 1-2hours then it "insanity" started getting repetative...supposably when you insanity bar gets higher wierder things start happening. Not true. The same things keep happening despite where the bar is at. The idea of going back in time and changing characters was fun though, different moves, worlds, puzzles.
