Tho i mostly ignore how my character looks.
The only execption is the mop hair character.
Also known as the rapist haircut.
Whoever designed that should be hanged.
Usually yes, I prefer a faceless one. I don't think of the MC as myself, but still, some kind of pseudo-me, if I can (there are choices, I can be not a real asshole, etc.). And I can't relate to the most "faced" protagonists, their body (fat, musclehead), their smug faces, their stupid hairstyles.
But there are games, when the MC has face, and real personality, and it's a joy to play him, even thoug he is almost not me. Like in The Last Sovereign, Simon is a better hero then I ever could be.
