So far every review I've read have mentioned the gorgeous 2d graphics and the solid gameplay system, and how it feels like an older RPG. Then they go on to state how it dosen't do anything new or innovative, but what it does it does great.
Gamespy gave it a 70%, but the reviewer seemed to have REALLY loved it. I'm a bit confused at the low score, but here's the final comments -

This is a game that, if you have the time in between the dozens of other stellar RPGs on the PS2, you will most likely enjoy. If you've been longing for a new Lunar or other old-school 2D RPG franchise to be revitalized for the PS2, then you most definitely should be giving Atelier Iris a look. It's a surprisingly solid package, and deeper than it looks on first or second glance.

They also mention how the battle system is alot like FFX, and that gets a HUGE thumbs up from me.
My gf is getting my preorder after she gets off work since she works down the street from Gamestop, so I won't know how it is first hand until then.
