The Witcher 3: Wild Hunt has almost arrived for PS4, Xbox, and PC. It's a action RPG game set in an open world.
Some of the best adventures in role-playing games aren't the ones the games script for you, but the ones you seek on your own, and The Witcher series does just that.
One of the best perks about this game (and I hope other devs take note) is that all DLC will be free. In the case that there is a paid DLC, it will be the size (or almost) of a whole other game.
