You seem to like 3rd person games, you got most of the good ones...I was gonna say siren, but nevermind
Stardust HD- It's incredibly well polished and has great graphics for a game it's price. Not to mention very fun to play. Flower is extremely unique, extremely pretty but more on the artsy side of things. If don't have a wii, high velocity bowling actually works a lot like a wii game where you bowl using motion controls, it's a fun game.
If online-only isn't too much of a turnoff try Socom and Warhawk, both unique online third person games.
Folklore is another game I love that rarely get's respect there's two demos on PSN, game has unique art direction - It's more of an action game than a JRPG, but does have a fair amount of text-only storyline. Valkyrie chronicles, does have a major Anime feel to it, I'll admit you might not like it if that's a turnoff to you. Heavenly sword is a very well done fighting game, you'd enjoy it. And everyone likes to hate on Lair, I know, but it's actually not that bad - they have since fixed the major problem with the gesture control with an update, it has good graphics and a great soundtrack.
