Quite a few good points there, I think Skep-tiker's is the most important one, there are all kinds of preferences and all will have games catering to that. And even if 99% prefer non tatted girls, why shouldn't the remaining 1% get one, too? As with women in real life, those in games do not cater to any person (except maybe the dev) specifically, you can take them or leave them, and as Elhesmere said, it is not like they are coming suddenly on day 79 of the story as a jump scare with every previously "clean" girl suddenly getting one. It's not "I want to play a game, dev make me one" but dev makes a game and I can decide to try it and like it or not. Giving opinions on how a game is executed is fine but if it's that close to being central talking about the basics is not helpful. More people like playing Call of Duty style games than pinball games, yet complaining on a pinball game why it isn't a shooter is pointless (I like taking that example because that's precisely what I have encountered once).
That being said, I also second Avaron's approach: while I generally do not like tattoos myself (and had a real life spat with my then SO about that, though it wasn't a deal breaker), here they come with the territory and are fitting for that and, unlike thread OP, I actually consider them nicer and better made than just random tats here and/or there. (Just, but that's an aside, as I think that the openness to sex, the somewhat silly bet notwithstanding, and the car repair girl not really fitting in there, is well integrated into the whole story and setting and way better than just "you go to college and everybody wants to fuck you".)
