I thought it was enjoyable, but not as much as Origins. I feel like with combat they took one stop forward, and two steps back. While they did make it more fun and fast paced, they ruined it by sending endless waves of almost identical enemies at you, with little to no variations in attacks, except for the rare mage or assassin enemies. Also, the high dragon boss in Act 3 was probably one of the most tedious, boring bosses in any game I've ever played. The half dozen dungeon designs that were used over and over again did not help.
I like half of the main cast. I liked Varric (He's awesome), Isabella (Yeah, I know that she is really annoying with her humor sometimes, but at least she isn't so serious all the time), and Merrill. Fenris was too broody for me, and they completely killed Anders for me in this game. Aveline is okay, but there's no reason for her to be helping Hawke after getting to Kirkwall because Hawke constantly is involved with criminals. Bethany was completely unremarkable, and the only thing remarkable about Carver is how much I wanted to murder his ass by the end of the game. As for Sebastian.. fuck that guy. Seriously, the DLC for him was a joke.
Story was unique, but not very well executed. I thought with Kirkwall being the only major location, it would change over time, depending on your choices, but nope. Very little changes over the game.
Act 3 is where the game crashes for me. Nothing you do has any effect on what happens in it.
