Are you only interested in isometric RPGs, or do you enjoy other RPGs?
I enjoy many of the classic-style isometric RPGs, but also enjoy many of the newer ones. Probably the best “blend” of traditional and new was Dragon Age Origins, which I would whole-heartedly recommend even to people who “only like real isometric-style RPGs. Other than that one things go non-traditional pretty quickly, but if you can adjust don’t hesitate to try the rest of the Dragon Age series, the Mass Effect series, Fallout 3, NV, and 4, or even Skyrim (not a very good RPG, but a nice open world wandering-around kind of thing), and don’t forget Witcher 2 and 3. All good, or even great, RPGs that you might enjoy.
Oh, and I don’t know if it will work with VorpX, I’m not quite there yet, but NWN2 is still a fairly good RPG even by today’s standards, and it did work with TriDef so there is at least some chance you can get it to work with VorpX.
