I have somewhere near 600 hours in now, and I can say that, while I have enjoyed playing DA:I, I have also been disappointed by the lack of proper fixes for a number of bugs and annoyances.
The KBM implementation, while workable, leaves both hands and right wrist a bit sore after a long session. I've remapped a number of things to make it easier, but it's still draining. The lack of (what I'll call "proper") mouse control for movement is more than annoying.
To give credit where it's due, the game is visually stunning, and on my PC at least, it works near perfectly. (I know some have had no end to crashes, though.) And the story line is both enjoyable and logical, to me at least.
All that said, it's been..... how many months since release? And issues in this thread and others still not addressed?
I'll certainly continue to play, at least until May 19th or so, since I preordered TW3 and its two expansions, but after that, if there isn't some serious improvement made in DA:I, I don't really see any reason to come back to it.
I've "won" the game a couple times now, and am replaying to more fully explore the game world (and again, to be fair, I am enjoying it), but there's only so many "go get X and take them to Y" tasks I can stand before I move on.
If TW3 is the hit that it promises to be, and they dole out all the free DLC and two adventures somewhere reasonably on-schedule, I'll be busy playing that until next year. Of course, if it's a flop, all bets are off. The authors of TW series have a good rep so far, though, so I figured it was worth the gamble to pre-order.
But I also remember being promised, and shown via official videos, a number things that did not (some of which will not), prove to be true in DA:I, so future purchases in the DA series will be after release, not before. You know the old saw, fool me once, shame on thee, fool me twice, shame on me.
