It's a bit tough saying something nice about the game on this thread, so I won't make a long post.
I'm sad for the OP that the game didn't work out for them.
It's certainly the game I most enjoyed the most in 2014, I've completed 3 play throughs, and I am really enjoying the multiplayer.
I've certainly put in hundreds of hours into it, though the Xbox counts time when you are not actually playing so I can't be sure of how many hundreds.
As DAI is BioWare's most critically acclaimed game this presents somewhat of a dilemma because despite the positive reception, it's not as excellent as it could have been and this why I think that is:
I think the move to Frostbite 3 was more challenging than anticipated and some of the features of DAO and DA2 have not been able to have been recreated in the new engine, which after all was built for shooter games.
The people most in a position to notice where the game was rough around the edges were actually the series enthusiasts, not the game critics.
Where it has hurt most is in the loss of even small cinematics surrounding some quests. Even a small quest can be memorable if there is a strong pay-off at the end of it.
Overall though, I'd put DAI on par with DAO, both are great games.
I enjoyed DA2, but that had some repeating content issues as we know, but it was still good.
To stay positive, I think DAI sets a good start on a new engine, for the future, if the game engine can be finessed, improved, and some of the features that people have commented on that have been lost from previous games, some more Tactics options particularly, then with the right writing DA4 will be outstanding.
