Finished it last night
Combat: Virtually always having enemies spawn in waves and out of nowhere got extremely tiresome very quickly, it felt like lazy design. The combat I didn't care about a lot either, it basically boiled down to "fire off a few AoE abilities and then single target the survivors down". It also didn't help the combat aspect of the game that there were so few types of enemies, fighting slavers, templars, mercenaries and thugs all felt exactly the same since they all consisted of archers, assassins, "sword+shield dude" and "leader dude".
The Story: Didn't like it at all, in DA:O it was this big epic adventure. But in DA2 it felt like each Act had a small, isolated "main" story that was padded out with 80% filler of you doing boring sidequests and ended up feeling like mundane daily tasks simply because they kept having you run through the same places over and over and over.
Locals: Again, in DA:O you went on this epic adventure that took you to a lot of intersting places. In DA2 you run around in Kirkwall, Sundermount, The Wounded Coast and like 3 types of caves. And despite of you living there around a decade supposedly, none of the places really change, I think the biggest change I saw was that in one of kirkwalls locations, some City Guards got replaced with Templars. To make the tiny amount of places worse, they didn't feel very different from each other, they really felt like they were located close to each other geographically. Of course you could say that it makes sense since the game focused on Kirkwall and the land just outside of it. But it's just boring as fuck trudging through the same looking places again and again for 30+ hours.
Graphics: It might look better than DA:O on consoles, I really can't say since I played both on pc. But on pc it really doesn't look better. Everything is so fucking low poly. Honestly, running through places like Sundermount and The Wounded Coast made me think there was a tesselation option in the game I should be turning on. and in Kirkwall everything is of a very angular design, a very "convinient" design choice considering the increased focus that was put on the console versions for DA2...
Characters: They were a very polarizing bunch for me, some I really liked, some I hated.
Liked: Isabella, Aveline, Bethany and Varric. Party banter between them were great, probably the best part of the game for me.
Disliked: Fenris, Merril and Anders. Annoying bunch of people, and poor Anders especially, went from best character in DA:O to one of the worst in DA2.
Conclusion: It's paifully obvious that this game had a very short development cycle, there is so much in the game that just screams rush job. It's a damn shame.
