For me, its the fact that its open world and you can explore, the problem is that there is nothing in these games to explore. Such big worlds and they are empty pretty much. Maybe a cave or whatever, but then nothing in them to keep you interested. Yet, even when that happens, i find myself still exploring but never really coming across anything cool or special. In the end its a huge waste of time. Or like Ubisoft, they throw in so much repetition on getting 100 of this item or 200 of that item. I tend to never finish the game and lose interest.
