I must be the only person in the world who expects a game to stand on it's own merits. I don't care what came before DAI. Don't get me wrong. I played and played DAO. If I was needing a DAO fix, I'd play it again. I don't need or want DAO 2. I played DAII several times. I don't need or want DAII 2. When I buy a new game, I want a fresh experience that either advances the state of the art or breaks new ground in the story. I prefer to get both in the same game. As for gameplay, I can game any system if that's what I want to do. Eventually there will be a playthrough where I do exactly that. I had to restart DAI because I found myself making poor roleplaying decisions, chasing approval. It didn't take me long to figure out that was a dead end that would suck the enjoyment out of the game.
I play a game, even a sequel, with a fresh idea of my goals. I don't care a fig about lore. I don't care a fig about realism. In a single-player game, I want to be the biggest dog on the porch by the end of the game. If I can't play the way I want, I won't play.
After a rough start, DAI delivered on my expectations from Bioware, which is to be entertained and only to be entertained. IMNVHO DAI is an excellent game. Disagree if you want to. I don't care. There is no reason you should care what I think, either. I'm just sayin'.
