Agree that the whole "cuckold confessions" setup just smacks of no imagination by a dev, and is really best left to NTR paths involving "cuck-in-a-corner" tropes. That's not a sharing path that I ever enjoy. If that's the dev's sharing path, I'm out.
Sharing games, for me, require a totally opposite setup, where MC and FMC actually find each other desirable, with both being "hot" or desirable by others, but for some reason (dev imagination/creativity required right here) want to experiment with the idea of getting involved with other partners. Preferably with action for both, with both wanting to encourage the other and get involved.
Far too many sharing games suffer from the "dual-path" issue where the other path is just a cuck-NTR, and to save renders, the dev wants the sharing MC to still be a cuck too. That's a lazy dev, and not much can save the game from that point on, if you try the sharing path with the idea of not being treated as a cuck. Those setups have fucked up the whole genre, simply because it is such a common practise, and those games have been a success NTR-wise, so other devs believe that is the way to go. Then we all suffer....
Exciting Games, TACOS, ALWL and a few others have better setups, (you can argue over that a lot) where the idea is one of excitement and adventure for both partners, with a common goal of sharing, not just all about the wife/GF becoming a slut and you being a cuck, though she usually gets more screen-time, simply because of player demographics. (TACOS has quite a few scenes involving MC/FMC/others together, and you can stop the cheating, or at least have the FMC describe her activities, you can even monitor her). (ALWL and Four on Vacation are great examples of swinging game setups for mine)
The multi-path games that are really just setups for the "main" one being the NTR-cuck are just huge red flags for me, because its a 99% certainty that any sharing/swinging path is just a lip-service alternate designed to get a wider range of players, and an excuse for dev to say "NTR is optional". (WoD though promising a couple of wholesome non-cuck paths, rings those bells too, so I am not playing it yet, until clarity appears) (The East Block has the same issues for me)
As a side-note, EG's recent updates are expanding on the idea of MC becoming a Stag to FMC's Vixen, and he has never been presented as a cuck (at least with my choices) If the game continues along this path, we should see some swinging or cuckquean activity soon, to add to the current Hotwife scenes.
So, I much prefer a single path game written by an honest dev who sets his tags right, over some multi-path one where I have to thread a needle just to see the few scenes where it could actually be considered as non-cuck sharing, in amongst the plethora of full-on NTR scenes with the MC being an obvious cuck hiding his little cock. Yuck.
Unless.......FMC is a total smoke-show, playing a whole field of wild scenarios, with nary a mention of MC, and no humiliation or cucking involved. But that ain't sharing, it's just a slut-game, a totally different beast to me, more about whether or not she has permission, and if she even tells MC. That can easily describe TACOS to some players, I know, though YMMV about the "smoke-show" bit, which is over-played in that game.
