TheGrimLord: Several of us get up in the morning or whenever and check the website for new release titles. These normally appear on the front page with sale announcements. However, there have been a few games which may have risqué art, designs or titles that may be a problem for those who have a family computer or children present in the room.
As of right now, I haven't seen anything too naughty (Kurokami-sama's breasts appear to be covered on the home screen) but there were a few titles like Being A DIK which did show some rather racy imagery. If one was married and the wife walked by, one might have to do some serious explaining.
Those of us who avoided bad decisions shouldn't be subject to those who made them. That should be their problem, not mine. Easy practical solution though? Avoid the front page and use the forum to get news of releases.
As others have already suggested, I see no reason (other than "the cultural conditioning factor") to distinguish these games from other, allegedly "harmful" games. DOOM and Mortal Kombat are now viewed as classics, but to people somehow unfamiliar with them, would likely not be considered wholesome fun-for-the-whole-family entertainment. Many people have criticized the game Tonight We Riot, which I believe may have even been on giveaway at one point, due to its themes of rioting and property destruction. To take an example from a different perspective, I would not say I approve of society's pro-police propaganda especially to kids who have not been made aware of alternative views, yet SWAT 4 is constantly in the bestsellers and has often appeared on the front page.
I do get the response that, essentially, "the adult games are what's controversial now, so let's just make a filter for them regardless of if it's consistent with anything else, since it will stop the current controversy." Aside from the slippery slope that people will then just get offended over something else, needing to filter that, and so on...there is still a very real problem in defining this "adult content."
The Witcher 2 EE, aside from mature content in the game, contains a bonus goodie of "Triss Playboy" which depicts said character posing nude and provocatively. Yet...gasp!...no one is calling that game "porn for virgins" or other such pejoratives. Presumably, GOG does not want Witcher games hidden behind a filter, especially if by default, lol. How can this be resolved? Edit: perhaps The Witcher 3 as mentioned earlier in the topic is an even better example!
Best solution to me is for the user to be able to hide individual games, not a filter across the board which inevitably can't solve the edge cases I mention above. Btw, thanks for a great post with your OP yet again.
