Of course it is. But not because it's a "top seller" does it mean it's profitable, though. They might just break even and they're gonna have to choose their next project carefully, if Steam gives them the axe, it's over. So no, it's not gonna lead to more being translated as long as you people are still here pirating the games. Want more lolis? Go and buy them.
However? Apart from you weebs that eat that shit like cupcakes, it's going to be a hard sell for everyone else.
Just like you don't want to be sucking dick in your harem cringe, normal people don't want to be forced to jack off to lolis.
Which is why I'm saying that they should just separate it. Same company, two types of games. One for normal degenerates, one for "neoteny enjoyers". The money they get from the normal games will fund their lolicon ones and vice-versa. Then everyone is happy, it's win-win for everyone involved, there's literally zero downsides. No one is forced to see stylized depictions of children being raped and tortured and you have a whole game of nothing but that to enjoy to your full pleasure.
I don't know why you're against this, actually. It's literally the best solution.
