There's very little to dislike about Witcher 3: Wild Hunt so it's very deserving of a place on this list.
It boasts a huge open world to explore along with a great combat system and more enemies than you can shake a stick at. You'll get your money's worth here as we've sunk over 40 hours into it and we're still not close to finishing. In fact, you'll need about 200 hours to complete every quests, side quests and collectable.
The graphics and dynamic weather effects are great additions and the sheer size of the open world means that you’ll have many, many interesting and un-scripted experiences while exploring.
