It is the most boring, yet exciting game you will play. Some sections DRAG out and seem to only exist to prolong the story... However, that story is deep... I found the menus overwhelming at start but after a couple of hours it was easily understandable.

ps. the whole snow sections suck... Make sure you use the zip lines or install them as you go, you won't regret it.
