I would petition to add these tags but the more I think about it the more complicated it seems to me. First of all, what differentiates stag games from cuck games? At first I thought that stag is "wholesome sharing" and cuck is "sharing and humiliation". But then I remembered a game that evokes conflicting feelings among players with whom I discussed it -
From Wife To Wench. On one hand, nobody humiliates you directly there. On the other hand, you are constantly hinted that you are a lesser man, e.g. you can't make your wife cum during sex unless you describe her lewd scenarios where she fucks other men (and centaurs). On one hand, wife is loyal, on the other - it is clear that she likes other guys sexually more than you, and there are all kinds of cuck tropes - BBCs, BNWO, the protagonist with an extremely small dick.
So what is that? Indirect humiliation? Maybe better call it "self-deprecation fetish"?
I personally feel that this game is very cuckold, but a lot of people tryed to convince me that this is actually a very wholesome game... Anyway, while defining stag as 'wholesome sharing' seems perfectly fitting, defining 'cuck' is more difficult.
Another problem with that categorization is that we will need to introduce the "netorase" tag to mark japanese-style sharing games. Because games like Adelaide Inn, Blurring the Walls, IMO, don't fit narratively into 'stag' nor into 'cuck' categories. Indeed they are Japanese-style sharing games. Although Blurring the Walls is an outlier even among Japanese NTS games, but still I think it rather belongs there than to stag or cuck. What do you think
Pr0GamerJohnny is Blurring the Walls Japanese sharing game or western one
narratively? I noticed in the comments that you enjoyed it quite a lot, before it went too much lesbian.
So here comes an even more difficult task - to define "netorase" and how to differentate netorase from cuck and stag games.
I kinda understand why the forum mods just slap "swinging" on all these games, tbh.
