I can see how this game has earned a cult following. It has easy and satisfying hack-and-slash gameplay with AI party members without micromanagement. Classes and skills are as you'd expect and character creation is pretty good. The story is your usual fantasy game fodder and it's not as "open world" as it may seem but the universe still feels alive enough. Dialogue is fine if you don't take it too seriously and the game has the spirit of a jrpg in a western body. This game was originally a ps3 title and it certainly feels like it today. The PC port is lazy, with poor support for the mouse making everything feel even clunkier and harder than it has to be (such as inventory management and even opening the map has you going to the esc menu first). The gameplay loop is pretty repetitive and the difficulty can be erratic - you might get mobbed and decimated from bandits and you might also jump on the back of a boss and kill it with no strategy. AI party members can be frustrating. If you don't mind the clunkiness of action games in the early 2010s and you're after an hack and slash rpg which doesn't require all your brainpower, this game is worth a look on discount.
I completed the vanilla game with ~100hr on console and later wanted to play the expansions on PC. GOTY edition makes this possible by allowing you to start a new game at level 30-something (with decent gear, items and unallocated ability points) in a world where the main storyline doesn't exist however all vanilla side-quests and the meaty expansion quests are playable. A handy convenience and incentive to jump back into one of the most polished action-adventure-rpg's ever
