I really Can't comment on DA2, only played Origins, and still play it through, I love the Characters and their conversations. As for the problems you say you were having with the game?
There must be something seriously wrong with your play style. I mean I had to repeat the ogre in the tower a few times when I first played Origins. But you get the hang of it, like by the third time? if you don't Well go play halo, or something stupidly easy. Some games, like I myself have come to realize need to be faced not as an action dismembering parade, but a carefully created tactical encounter. some of us have fun with it, others don't. It a matter of personal opinion. what happens is that your opinion doesn't make the game bad, the game i suspect is really good, I myself will have to try it, you don't like the game, well nice for you you found a game you will not be spending your life on, as for others that enjoyed it, good for them as they are having fun playing something. You really shouldn't waste your life, or others's with threads like this. YOU don't like the game, it didn't appeal to you. OK too bad better luck next time. Don't go advertising the game as a sucky game.

PS good luck with other games.
