Let's see...

Skies of Arcadia: Nearly everybody (including myself) who has played it will say that this game is a masterpiece. Sure, it has a really clichéd story, but it does it so well that it makes most other RPGs look bad in comparision. The soundtrack was wonderful, but how it got butchered in the GCN remake is an unspeakable crime.

Okami: Almost everybody has complemented on this amazing game. I have not played it yet, myself. Because of this game's low sales causing Clover to dissolve, that's a real failure of the consumers.

Psychonauts: I haven't played this either, but nearly everybody who has played this likes its quirky nature. There's something wrong when a crappy Jaws GTA clone doubles the sales of this game.
