If you are trying to beat all the side missions it takes at least 30 hours, plus 25 hours for the main quest (50-60 hours of gameplay). Ive been playing for 25 hours and Im about 50-55% through the story and only 20% through the side missions. There are 300 side missions, some that can take an over an hour to complete. The reviewer said the side quests only add 10 hours to the game. Obviously hes wrong. All of the really sweet loot will be found through the side missions, as well as epic battles with monsters much harder than in the storyline quest.

Also if you play on HARD the game is much longer as well because the average battle will last longer (more HP for enemies). I'm pretty sure the reviewer played on NORMAL.

Overall this is a great game for fans and new comers. For best results play on hard.
