DAI returns to form, I agree and disagree. I think DAI is 1 step forward and 1.5 steps backwards. In terms of what Bioware has done recently, sure it's a return to form but what does that mean return to form. A return to a mediocore Bioware that's nowhere near the strength of Baldur's Gate, KOTOR, Mass Effect or DAO, that's what I see from DAI.
DAI tries to be the best of both Skyrim and Origins and fails at both although that doesn't mean DAI is terrible, much like Die Hard 2 isn't terrible it just isn't as good as the 1st one. Skyrim allows you to fully explore a game with tremendous freedom and good exploration although it suffers from bad writing as well as couple other design choices like no attributes, etc. DAO has great writing and great replayability because of choices that do matter. DAO though is very linear unlike Skyrim which isn't, plus it takes like 6 hours to get to Lothering so it starts slow but like a snowball rolling down a hill, it gets bigger and better.
Now with DAI, you have good exploration but it's quantity, not quality exploration which DAO had and that is the main problem I have with DAI. DAI is more quantity and not quality. That phrasing goes to more then just exploration, it also goes for the writing which is probably the worst in a Bioware game to date not named Mass Effect 3.
Let's look at Coryphy, when let your heart shall burn or whatever the quest he appears, it's a pretty epic moment that sets the stage for an awesome 2/3rds of the rest of the game but what happens, Quantity and that's the main issue with DAI. Corphy fails to deliver and you have a less then epic ending, you have kind of a mediocre ending which is not what I expect from Bioware. I play Bioware games for quality, if I wanted Quantity, I'd play Skyrim which is stronger in the areas that DAI tries to be strong at but fails.
Lastly, DAI has great companions but due to the way the game is structured for quantity and not quality, the companions are kinda meh in the end, sure they have there moments but once you do the side quests then what, like Blackwall, once his stuff is done there's not much to do with him.
DAI is kind of a step forward, if you like a mediocre Bioware that doesn't make games up to the strength of the Mass Effects and DAO's of the world. If not it's certainly a step backward and not the return to form that Bioware believes. I'm cautiously optimistic that ME4 will be better due to current gen only but I need to see that in action 1st before I believe it.
