the 'edgy banter' is still there, it just depends on who you bring with you, just like Origins, Iron Bull, Dorian and Sera are always good for a laugh.
I found the story well written and interesting, in my opinion it's the open world that let's the story down. BioWare try to build up tension and create a sense of urgency but it doesn't work as well when you can spend hours messing about between story quests.
The environments are beautiful and well designed, even the ones I hate navigating like the Forbidden Oasis are beautiful to look at.
The companions are varied and interesting and each has their own plausible inner life that you learn about throughout the game. In many ways the character interaction is more interesting then in Origins, for example
I miss the AI tactics in that was in DA:O & DA2 but overall I prefer the combat in DA:I to the combat that was in DA:O. Although it did take me awhile to get used to.
I've just finished my first playthough were I did pretty much everything, in my next playthrough I'm going to stick to story quests and important side quests to see how that compares.
Overall though I've really enjoyed my time in DA:I so far. I can't say if I prefer it to DA:O until I complete more playthroughs, it's only fair since it took me 2 playthroughs of DA:O & DA2 to really see what was so special about them.
