Actually if you think back to when DA was first coming out, they said that it was the spiritual successor to Baldur's Gate but more dark and gritty, which DA:O was.
The combat wasn't very "interactive" as my hubby likes to call it, but it make you think and use foresight before rushing in, the mages in DA:O could be a pain in the ass at hardcore and nightmare difficulty, the curse of mortality and prison could easily kill me, if a mage didn't have dispel or I didn't have a templar handy. And lets not forget the Dragons (e.g High dragons and Archdemon). So in short yes I liked it

That is what I dislike about combat in DA2, I mean the new combat style is very nice but it could have been so much better if got to keep some of the tactics, honestly more often then not it felt like playing DMC4(Devil may cry 4) that my hubby loves so much (shudders), sure the new moves are more flashy but there isn't a single challenge in the game if you up the diffulty all you get are more mobs that turns the game into a hack and slash game (which for me is very boring).
Story wise DA2 plays a little to much like ME2 - I don't mind it devided into Acts,or the little "rush feel added to the story" but I am sadden that the companions are lessens the way they where in the game, you learn so much about your compainions in DA:O compared to DA2 and the only one I could really relate to was Anders - boy did he break my heart with the hole Chantry thing lol ( and no, 6 out of 9 times, I just couldn't kill him XD)
Fenris was sort of, well hard to get to know, but I liked him by the 3 time I played the game, I know ppl complain and say Anders whimes to much about the plight of mages but Fenris is just the same but magic is bad, very very bad - Even when he romances a mage! lol ( Hipocrit lol)
But sorry didn't mean to write a small novel XD - My point is that both games have something to offer and everyone will have different opinions.
For me, would love to have a better combat in DA3, doesn't have to cater to hardcore gamers but is it to much to ask to have a Boss fight to actually be a itty bitty challenging?
And the story...while not bad, it could try to invoke a feeling or something XD
