Biggest issue with DA2 was it felt like a fucking video game, with the mobs warping in in waves. There was zero room for positioning strategy in that game like the first one had. DA:I had the same action emphasis issues, but at least the mobs didn't spawn in in waves like you were playing a 1980s arcade game. Also, some of the ending parts were massively retarded, lacking anything resembling real choice. The game had some real sloggy parts to it, as well. DA:I kind of improved on that with the semi open world and the war table (good idea, execution with mandatory waits was retarded) making things less on rails. DA:O was a great game for its time, but it has not mechanically aged well and the story is not especially better than the later titles. I preferred it over 2 by a longshot and DA:I remains the most replayable one for me, at least.
