I've been playing a bit of DA2 here and there when I'm able. I'm actually really enjoying it, too.
Is it fun? Yes. Is it better than the first? In some ways, also yes. But I have to agree with the sentiment that this edition of Dragon Age is somewhat of a step back in one area: story. At least a few hours in.
I'll be the first to admit that the action of Dragon Age: Origins felt too old school to me. I just lost the love of those games a long time ago, probably after Arcanum sold poorly and Troika went under.
So when Dragon Age 2 was announced, I was excited that the combat was being given a long hard look. I'm actually somewhat pleased with how it turned out. I can still pause and issue orders if I want, but by and large it feels a lot more like I can control my character in this one. I like that change. Others miss the party-management, but really it's still all there. You can still take control of any character at any time and issue orders. Similarly you can set their behaviors and never look back.
It's not at all unlike the changes that happened to Mass Effect 2 from its prequel. I honestly feel (on the PC) that DA2 plays better. It's more interesting in terms of combat for me than it was in Origins. I used to loathe the combat in DA:O, and would instead wait eagerly for the story-driven aspects as cliche as the tale was. It was still gripping.
The big difference with DA2 is that after a pretty solid lead in (mind you I'm only in the first few hours of the game still), I'm not grabbed by my character's tale. In ME1 and ME2, I was immediately hooked and both games kept me playing until I beat them much to the plight of my dogs and wife. In DA:O, I was hooked on the story in a more gradual way, but I was still hooked. In DA2, despite the increase in fun I'm having with the action, I feel like the story's kind of dull. I'm skipping chatty scenes... in a BioWare game. That just doesn't happen with me.
Hopefully it will get better as I play more.
