I guess I'm a bit late to the party, but I'm deeply in love with the Dragon Age Series so I kinda feel like I have to throw in a few words.
Personally I enjoyed my main playthrough immensely. I was never really one for the mage type and usually preferred dual wield rogues, but after about 70 hours of my first playthrough I restarted with a mage and had no regrets. It's a fun class to play, if sometimes disappointingly easy, compared to the rogue. But still, nice class to play.
But more than the gameplay, the characters and atmosphere managed to capture my heart. I probably spend hours just talking to my buddies and grew incredibly fond of them. That's a big fat plus for the game. Of course, there was also romance, and what can I say, as a girl I just kinda respond to that kind of thing very well and it contributed massively to my gaming experience.
Other than Skyrim, DAI made me feel like a hero, like someone people rely on and look up to. I felt responsible, and compelled to always make the right decision. I admit though that the game doesn't leave you a choice really. Other than in DA:O or in other games (yep, like Skyrim) you couldn't really find and model your own path through the whole ordeal.
As the previous poster stated - world and story are a lot more static than trailers and bioware talk make you believe. That's a huge disappointment for me, as I loved DA:O and how much I could influence my Warden's path and the world around them.
As a result of the previously stated, I feel like I'll never enjoy another playthrough as much as my first (complete) one, DAI does not have a very high replay value for me. So yeah, I agree with Raijin on that.
Still, I'm a Dragon Age lover and DAI did manage to touch me and captivate me. It's also damn pretty.
I think people who have played and liked the previous Dragon Age game are much more likely to enjoy DAI - because of the characters, because of the backstories and because it makes you shed a few tears of nostalgia in memory of your warden. Especially at the tavern, when THAT song comes on.
Yup.
