I have a big problem with a game that has a faceless MC or we only see the half of his face, it feels very unnatural and kinda putting me off a bit. The thing is, as some have said, I don't insert myself into the MC role because at the least the MC has his own personality, even the blandest MC does have one. Every time something happens, I always want to see MC's reaction and his expression because in many situations only his facial expression can react to those.
A faceless MC is very pointless to me, it provides nothing and even decreases the level of my enjoyment for the game, and the biggest problem is a game that has a POV kiss scene, for christ's sake! I don't really understand why they do that, it's just really weird and not romantic at all, seeing the woman pouting her mouth in front of you is ridiculous, and cringe af, so pls stop doing that.
Okay let's get back to the question, I love a game with an attractive MC, it feels more natural for all the LIs to fall for him and a good-looking MC is more eyes pleasing than the ugly one ofc. I am straight(mostly), but I also find males attractive, I have many actors that I think are handsome and really attractive. So ofc attractive MC really enhance my experience with the game. But, another thing is an attractive person is very subjective, and most of Daz Male models are really hard to find a good looking one that don't look like an asshole or with a rapist's face, that's why you'll see the same model over and over again in different games.
My example for a game with an attractive MC is Chasing Sunset, The fact that MC is a good-looking guy does play a big part in the story and it really enhances the game immensely for me.
