Map is too large and interactions are too little... at least Skyrim has engaging storyline from the onset.
I felt no motivation to finish the game (lack of storytelling)
It's difficult (frustrating), nobody wants a game that's too easy, but this tips over the border of a huge waste of time.
So if you've got nothing better to do IRL and prefer to go for long walks in huge (poorly rendered) digital landscapes... this is your game.
I have real goals to accomplish, I won't allow games like this to turn my children into goldfish.
