I mean he looks pretty human to me, and he sleeps with all the hot girls what's he missing out? If you watch say, X-men at least you get it that ok some of the X-men get alienated because their powers are scary and stuff.
If I had to guess why it's probably because of the protagonist, I hate the protagonist, he's so boring so unlikable I have zero sympathy for him yet he won't stop bitching about having super powers and therefore 'not human'. I honestly cannot think of another game that is less than 10 years old, highly praised, and I do not like.
But I just can't get into it for some reason. I am not here to hate on the game, I really want to enjoy it too, I wish there are more great games for me to enjoy, I want it to be good. Obviously it has been widely accepted as one of the best games ever made, but I just don't get it.
