This is a large-world RPG, with many characters, long story, and many relatively interesting environments to explore. In few places, I had almost an "epic adventure" feeling such as when playing Baldur's gate . However...
There were two aspects that considerably reduced my enjoyment of the game:
a) The story progression felt a bit ridiculous - one starts as a relatively ordinary dude, and after a couple of hours, bam, you're the person to reunite everyone and save the world... argh, not again. I am ok with the world-saving motivation, when it's done subtly and over many hours of gameplay. But here, you're given a mega task even as a pathetic little thing that gets killed by three goblins, when the world is apparently full of much greater heroes.
Also, as much as I like to help underdogs, help people in general, fight injustice and discrimination, etc. etc., some "social justice" points in this game were just cringeworthy and pathetic. That's not a good way of serving such a difficult and deep topic.
b) The fights were just not too much fun for me, but there was a lot of them and they were one like another, with a couple of exceptions. In Baldur's gate 1/2, Fallout, KOTOR,... most fights would be in some way at least a bit unique, you'd profit from different strategy, etc. For some reason, the combat systems in "new" reincarnations of older games (i.e., DA, Pillars of Eternity) don't work so well for me.
Graphics is a minor negative for me - I prefer a pretty detailed 2D over a relatively ugly (and unnecessary, gameplay-wise) 3D.
Overall, it's a pretty good game, but not more.
