sure, but common sense dictates you go for the bigger group of fetishes.
like, what do you wanna bet what people like more, fatty women, or elves? or stockings? or just normal milfs?
The thing is, there are hundreds - if not thousands - of games that all cater to the wider audience with regular MILFs, elves, skinny girls, etc.
"Thick" girls like this are fairly rare in these adult games in comparison, and sometimes it's worth it for a dev to go all-in on a niche to appeal to a singular market that is under-served, even if they don't appeal to a wide market.
I mean, it's not like it's going all the way like games like MetF or any of the handful other full on BBW games (which themselves are few and far between and cater to their own very specific niche), so it is really targeting people who are into the "extra cushion for the pushin" look, but aren't exactly a fan of the extremes that the BBW games go to.
It's certainly not going to be for everybody, but if the dev is into it, then they're probably going to stick with it, and I think it's a positive to have something *different* rather than just another copy/paste using the same generic daz/honey select/koikatsu models that every other dev uses with just some hair colors/choices swapped around, with all the girls basically looking the same shape (thin, in shape, with nice butts) and only their boob sizes changing depending on what kind of game it is.
