The Elder Scrolls V: Skyrim
Is that Max Von Sydow providing narration?
I've been playing Elder Scrolls roleplaying games for over 15 years. No other series allows the same level of freedom; you can follow the main plot, if you want to, but you can also go live in the forest hunting deer and picking berries, or live the life of a thief, making a living breaking into shops and the houses of town nobles (not that I condone such behaviour). These games always provide a terrific sandbox for roleplayers. I can't wait until 11.11.11
