The primary way the story is presented when playing the game as it is intended is indeed lackluster, I'll give you that. Then again, had it been more detailed, you'd see even more complains from those that simply do not care about it. However, luckily there are plenty of alternative ways of dipping into the lore, and the way the universe has been expanded since Diablo II is just magnificent - if you look well enough into it.Quote from phatosen
Diablo 3 is a great game and I still find many hours of enjoyment from it, but the story... Being a lore geek, the story/presentation alone makes it so this game doesn't deserve a title like that. Unfortunately.
Without sidetracking too much from the original topic, I agree that Diablo III doesn't deserve the reward of Game of the Year by a long shot - but it is indeed turning better and better.
