I've just been playing "Remember Me". Love the art style, the fighting, the setting. Almost everything about it. But it seems it never got much attention on release. Indeed, I wouldn't have played it except for PS+. The developers didn't feel there were enough sales to make a sequel which saddens me.
And another one is Kingdoms of Amalur. But the developer went bust so there won't be a second one of those.

You may want to look at the Drakengard series though (I think it may be PS3 only however for 3, 1 and 2 was PS2 I think?). There is supposedly some connection between the worlds of Drakengard 3 and Nier, but I don't know what that is as I've not played that either yet, it's not a sequel but again maybe worth the look if not already
