I really hate DA2, not only because of carver but because there's only like 6 different dungeon designs throughout the whole game that are copy/pasted with superficial differences, like passageways that are closed off in one copy of the dungeon, but are open in another.
The fact that there is absolutely no new information or events concerning Darkspawn also made me go wtf, and the fact that Flemeth is still alive despite killing her in the first game just pissed me right off.
I also hated how they fucked with combat. I play on a console, so instead of how it was in DA:O where I could just press a single button once to keep auto-attacking until the enemy was dead or I decided to stop, they changed combat into a crazy button-mash fest in DA:2. I have to tediously keep mashing the same button in order to perform my generic attack.
I honestly saw no purpose in this game... it didn't advance the plot at all (as far as I can tell) and it was just a series of boring copy/paste dungeons.
I most likely won't play the third game, but if I do, I'll either rent it or borrow it from a friend.
