I played the game when it was released and due to outside factors dropped it. I started a new game about a month ago and have now clocked 50h+ of game play. The patches have massively improved the game play. The plot while slow to kick start, gets into full gear around the start of Act II. Game play is solid, combat is challenging at high difficulties, the sound track is great, and the lore immersive. A few "bad" things: gold is plenty full, you will never need to save money for anything. The party AI is weak but kinda irrelevant as on easy/story mode the fighting is easy and on harder difficulties one would want to micromanage. Fast travel allows you to move to a location, but not within it so a little time is spend moving from A to B within a map. Combat can be daunting on new players as there are a lot of effects happening at once: use pause, read. Overall, no major problems and lots of good things.
I played a few hours of the game so might not have gotten to all the irritating features. However, it is refreshing to see a game where choices matter, where you need tactics, and where character interactions do matter. You might have to play a little before getting a ranger party that actually work but that's just replay value. Quests are engaging, fun, and full of choices. The game itself can be complex (How do you stop bleeding again?) so reading the manual and tool tips is important.
