Certainly not the best RPG I've ever played.
It just sadly/hopefully has the foundation to be, after all patches and DLC, at least one of the best RPGs I've ever played.
Foundation. There's so much STRUCTURE here for greatness, but its only half achieved in core DAI and the JoH DLC only seems to address some things, not fully advance most/all things.
So much COULD be done, in extensive and cool ways (even if with a pricetag), but whether Bioware will do it is a whole other matter.
So far I consider the game good to very good (compared to DA2's mediocre to good, and DAO's very good to great). That's fine. Glad I've been playing it. Now devs, I hope you have more to come to really kick ass with - especially in gameplay and story (art/graphics are largely more than fine!).
DAI will never be my outright favorite RPG though. I'm alright with that. I just have several things in my head that I think DAI COULD do, and I think would be fantastic if it does do them. Core DAI itself may very well be a warmup for more. Or not. JoH and recent patches indicate things could go either way, heh.
