I suggest you take a look at the PlayStation Network if you haven't already, because there's a huge selection of games you could be playing that aren't shooters. You can get some pretty good deals (discounts and the like) on a lot of them, if you buy PlayStation Plus ($50 for a year). Some games are even free with it. There are tons of PS1/PS2 games on there that you can buy and play, as well.
You're probably aware of this, but Disgaea D2: A Brighter Darkness comes out on October 8th. And if you're a fan; Hatsune Miku: Project DIVA F also becomes a choice on August 27th.
The Atelier series is great, but I suggest anyone to stay away from Ayesha. It's garbage compared to Rorona, Totori and Meruru.

Since you liked Borderlands, you might also like the Ratchet & Clank series.
