I happened to restart playing Genji 2 over the weekend.
It's not as bad as some reviews said. It got bad reviews mainly because of the problem with its camera angles. It takes some time to get used to it, but certainly is not "unplayable". For me, it's gameplay is a little bit hack 'n' slash but nowhere near the level of the Dynasty Warriors series.
I like this game and I think Genji 2 is one of the best looking PS3 games out there. The environments and characters look amazing. If you like the art design of Folklore, you may like Genji 2 as well 'cause both games are made by Game Republic. Genji does not have the flow and fluidity of other famous third-person action/adventure games on PS3 (Devil, Heavenly, Ninja). However, if you can find it cheap (I once saw Fry's had it for sale at $19.99), why not treat yourself some eye candy?
It (PS3's market share) might hit 30%, but definently not more. ~ Neo
