DA:Origins is a good game. Not quite the same "feel" as BG, but still really good. I personally could not get into DA:II (I have tried multiple times, I just get bored), and I have not played DG:Inquisition so I cannot speak to it.
If you are looking for a spiritual successor I recommend Pillars of Eternity. It has become one of my favorite RPGs, and I think it "feels" more like BG than Dragon Age.
ShadowWalker56: I didn't know where else to ask this and not got honest answers. I know I could ask in the general forum but not sure how well that well that would go. I've heard that if one liked BG then one should play Dragon Age because Dragon Aga is a worthy successor. How true is this?
