I only played DA2 twice for real. It never really sparked with me. Can't say why, maybe it was the guys falling from teh sky that turned me off, or the deja-vu-dungeons (both issues are so much rectified by eh superb enviroments in DAI...that alone makes me realize that, despite any claims I amde in the past, graphics and locations DO matter in an RPG, at least to me...^^)
The story? Okay, and a new approach with the ten-years-span. But that was also the main problem, it made it harder for me to connect. There you are, killing the idiot Artischock and ... bam, Champion of Kirkwall, most important person in the City...a bit hard to swallow for me at least. And the whoel templar-mage-thingy came a bit too apprupt in the end. Yes, some build-up was made but..it never felt like the focus of the story...
In fact DA2 is/was nothing more than an elaborate Prologue to Inquisition. Red Lyrium? Templar-Mage war? Main Villain? If they now also had thrown in a Qunari-inavsion all would have been covered I guess. Or, if you believe in "Hawke was meant to be Thedas' Shepard", then DA2 was only an elaborate Origins-story for teh new rising star of Thedas that ... fell sadly on her face and was reduced to supporting role.
All in all, DA2 is for me only filler-material. The real meat is in DAO and DAI. I wouldn't mind though if tehy do such a game in-between the epic ones again. Not as rushed though, but more linear, focusing on a single char, telling a compact, not too epic story, in a location like a city with a bit of countryside.
Would be cool to have before DA: Blightstorm , where we wage war against the Darkspawn and their weird twisted newly-createdArchdemon while the idiotic Qunari are invading (and of course both are utterly vanquished! Hooray!). We'll be playing a Grey Warden and .. Ride Griffons!!! 't will be fantastic!
