Which are the games that I HAVE to own?

Thanks for your replies!

Ive heard a lot about the Pikmin games, same with the Viewtiful Joe games, I havnt tried any of them though.

I guess I should get Beyond Good and Evil, Skies of Arcadia and Tales of Symphonia, they all look like nice games - maybe too time consuming but nice, maybe work and studies have to stand aside for gaming for a year or two :)
