There are examples of fully 2D games that fit those standards, but we're talking about a few gems in a huge landfill. Hreinn games for example has Noxian Nights finished and currently they're developing the kingdom of deception. solid game, nice art, fully 2D, VN style. (tho people also complain about them being slow)
but to be fair, it's a reality that many western smut games end up unfinished, rushed, or onhold (basically milking). being concern about something like that is not a bad thing in itself and I personally understand it. what I don't like about these posters is accusing and pointing fingers, sometimes even insulting the devs and judging them based on absolutely nothing, because they just saw the version number and years passed and rushed to the reply section to rescue clueless people from the devs, WHILE NOT KNOWING ANYTHING ABOUT THE PRODUCT, IN A PIRATE SITE. jesus
