Best EZ to learn games for PS2?

Just got my first system. I will just be renting and won't have enough time to play anything that takes a lot of reading or getting used. So what are the best games out there.

Katamari Damacy

Fun game. A little out there, but a lot of fun.

any more?

any more?

kingdom hearts for $20

ICO, should be very cheap now

Yes, ICO is good.

Also try Prince of Persia: The Sands of Time. Its sequel (Warrior Within) is good too, but it might take you a while to learn the combat.
