It's a good game if you like RPG's with very involved storylines, a complex world that requires buckets of reading to learn the history of etc, if you like games that you just drop into a go, it may not be so great, but if you can get into the storyline and enjoy the atmosphere, yes.
Erm. I finished DA:O last night and started Mass Effect today. So far, I'm finding that DA:O does a much better job of explaining the way its world works as you progress. Like, I work for a council on a citadel, but I can't tell you a damn thing about who's on the council, how much power it has, how much autonomy the various races have (or whether there are any cases where a race is not some ridiculously homogeneous political unit) and so on.
Perhaps more importantly, no one has bothered to explain what this mass effect thing is and where my magic abilities come from, but whatever.
Incidentally, the voice acting is much better in DA:O. My PC in ME is, like, always pissed off. Doesn't matter what I'm talking about, or with whom, my character is always angry. And urgh, sometimes (like when talking to the council the first time), it's just painful. Like, mr PC, why are you so angry?
You don't have any evidence. What, you think they're just going to take the word of a random dock worker? Seriously? Are you twelve?
To a lesser extent, it seems like most people in this game are always angry. It's somewhat annoying.
I still enjoy it, mind.
