Beyond Good and Evil. I beat it. It's a good game.
Do you like Zelda games? BG&E takes the Zelda formula and makes it a lot better. There's a real story. The stealth sequences are a lot better, and I never got stuck.
It seems that Ubisoft was willing to admit their debt, since the town is called Hyllis, making the citizens into Hyllians. If you recall, Link is a Hylian. I don't know if it's a coincidence, but it seems awfully close.
There's a trailer for BG&E II on the dang ol' internet. Of course, like any good teaser, it teases you by not showing you the protagonist, who the company clearly thinks has a pretty face, since BG&E is designed to show you it again and again, both in game, and in cutscenes.
