1) ICO (Quite possibly one of the top five games ever made. Yeah, it's that good. A solid puzzler with great story, character interaction, and depth. And it succeeds at creating a sense of vertigo in the player.)

2) We <3 Katamari (The sequel that's more of the same just... a whole lot more of the same. A very fun puzzle game with tons of quirky japanese wackiness.)

3) Mad Maestro (Wow is this game hard or do I just have NO rhythm. Well, I AM white after all, so that's probably it. This is a super-cool music game that lets you be the conductor for a struggling community of musicians.)

4) Harvest Moon: Save The Homeland (Yes, I'm a guy. Yes, I love the Harvest Moon series. There's just something so satisfying about building up a farm, interacting with the villagers, and visitting the faerie. ...Erm, yeah, I'm a guy, I said that already!)

5) Gitaroo-Man (Oh yeah this one is seriously wacked out. You battle space aliens by playing a guitar. Seriously weird and psychedelic visuals ensue. And then there's your transforming mechanical dog.)

I sadly still haven't gotten to play Shadow of the Collosus, or that game would likely be listed on here too.
