This reminds me a lot of The Sims and it's progression in its series. 2 was the most charming and had simple graphics, but much to do with many choices, Sims 3 had an open world, but many bugs and lags and Sims 4 tried to replicate Sims 2 and while focusing on the new look it made them game dull and too easy.
DAI has amazing graphics, but it feels like they made the game less harder. Maybe for different ages or preferences, I don't know, but it's easy and like many said, outcomes are based mostly on dialogue and not actual action. DAO is the last game in the series I played after DA2 and DAI, and instead of a feeling of lacking graphics and gameplay, I became so involved and play it over and over! I love the choices you get for Wardens and each one has a different home and story (minus the mages). In DAI everyone is at the same place no matter which race and the same results happen no matter what you do, with a few exceptions.
I love DAI though, but I think they broke the mold with DAO and nothing will ever truly compare to it, unless they went back to that style with all the upcoming games, but things change and so we must learn to adjust.
All this being said, I am proud to own all 3 games and their DLC and allow myself to be carried away to this amazing world and meet amazing characters, and I'm thankful the series remains and continues with a timeline that connects so that when I'm traveling through Fereldan 10 years after DAO, I actually feel like I'm coming home.
