One thing to keep in mind is that in Hitman 2016 47 had the opportunity to walk the runway in Paris to reach one of his targets . It wouldn’t look right for 47 to follow that opportunity if he looked as rugged and fictional as he did in Absolution. He had to look the way he did to pull that off convincingly.
Also, some of the prototype images shown in that one thread reveal that 47 was going to look like a cleaned up version of the Absolution model, and it just doesn’t look right.
Technically, it’s not the same 47, as he doesn’t have the numbers on his barcode like before that gave him his name and disclosed his birthday. This is part of the design decision to make 47 timeless, so that he didn’t grow too old. I do agree with the personality of the faces though. We need more of that in Hitman 2.
