Sometimes I get confused, players are playing a a game where the MC has tattoos and then would be kind of weird if he wasn't into the tattoos of the girls but ok, probably there is some tattooed people that aren't into the tattoos of others.
MCs don't have to like things and behave exactly like any of us and they have their own personality, probably I don't like some of the decisions of the MCs in every game, after all it is a creation of the developer and they don't know each of us or like I want them to behave.
There is some choices that shape the game, there is some kind of levels of immersion but only to a point and usually developers can't please everyone and they target mostly the audience that is similar with themselves. Probably they like tattoos and they even have them themselves.
Also the way some say things/refer about tattooed and or with piercings some times make me flabbergasted (to not say disgusted) that even on that there is still prejudice. I don't have any tattoo or piercings and never will but I enjoy to see some if well done and with taste and with good art in others.
