No worries. Good enough, maybe. But if you compare it to other AAA games released this year it falls short on that department. I think before machines (consoles if you will) coudln't handle huge open world with great story and top notch graphics, you could have one or the other.
MGS, and even more The Witcher 3, has proved things have changed nowadays, you can have both. Of course when you buy a Bethesda game you know what you're in for. But It won't stop me from wondering... Bethesda today is huge, big production team, huge fanbase and marketing worldwide... Surely they could have made a better engine if they wanted to.
I don't mind how it looks, I'll play the hell out of it anyway. But I look at, for instance, that thumb on the last picture and I can't help but think a little more effort could have been put into the character models, the little details, you know. The world looks okay, character models not so good.
