Thanks for constructive answer.
I don't know why everyone skips the things I talk about and making some strange assumtions. Again, I don't care about any historical accuracy till it's explained. I don't try to show dev how he need to do his game, it's his business. But it doesn't take much time or text to explain the setting you present. You have you own nobility system, OK, tell us about it. A few words, as MC's thoughts, for example. You have modern gender situation in your setting, that's fine, tell us about it. And so on. I say it again, all we know is it's a fictional medieval world. And being the one who actually studied history in school and spent years in DMing medieval campaign with fictinal things like magic (and my players loved this campaign) I perfectly fine with any medieval world if creator of this world explained me differencies from default, even partly, in his game. When I see medieval, I expect medieval. With all the things you said in your message. If setting is medieval in it's core but has some unique features then please, good dev, explain that features for poor players who see not what they expect to see.
And, well, I don't expect to see many models in renders, that's why I never said a word about it. And if dev has no models for medieval underwear available (which I sinserely doubt, models of common shirt or long blouse I already saw) then I think it's quite logical to not use any. After all, in medieval times nakedness was not really shamed as in today's world.
I think it's because you mentioned those examples (nobility system, women's rights, ... ) pretty much at the beginning and only later explained that it's not about themselves being there but your wish for a setting explanation.
And I have to admit that I (because I read multiple comments, that actually were about historical correctness and started almost exactly like your comment, already) started skipping parts of your comment in the end, resulting in that wish for an explanation not being that prominent in my perception. I can just assume, that it was something similar for others too.
I think our approach is just different here. If I read a book about a historical subject or watched a documentary I definitely would expect them to be as correct and detailed as possible. Each movie or book I would expect to have a strong setting backbone which includes that it can work based on its design ideas and is in itself logically correct.
But while I do lament about wrong armors, weapons and a lot of other stuff including logic (in general in movies, not limited to historical ones) if it's too obvious or concentrated, based on the medium my expectations are just lower here regarding the amount of correctness and/or logic.
Therefore, in this case, I expected the 'medieval' to be just enough to give the game a little flavor - some coating on top of (based on Triangle) a nice, lighthearted feel-good story - not a completely though out setting (and even those of have large holes in their logic sometimes). And an actual story with a coherent enough plot-line. So everything medieval-ish I get is nice and appreciated - as long as it supports my expectations towards the rest of the game, assuming that everything presented is a setting definition in itself, supported by the environment even if not shown/explained in detail. If NeverLucky would start to introduce contradictory elements or the characters behaved implausible based on what is already established - that would be something I would have a problem with.
I had some stumbling moments at the very beginning - why is the MC the only one of 'color', why is he without an entourage, why didn't his squire learn to ride before - and why wouldn't he buy a horse for her first thing?
In the end, I accepted that the entourage wouldn't add any benefit to the story and only cost rendering time - like in almost any other game here.
Then the game needs to get the characters together - a familial surrounding helps to explain why they are this comfortable with each other in a very short time - it also allows them conversations otherwise impossible.
The horse thing - while his wife sleeping with her maid for warmth is plausible and helps to get them together, how is the MC going to do that with his squire? Always on separate horses, secure in inns, and in their own rooms?
The solution is to exchange the gym time with sparring and let them have some unfortunate bad luck outdoors. The shared horse just helps to get them closer before the rain. It's just one big effort to get the MC and squire close at the same rate as wife and maid. Definitely the most cringe-worthy element here - but at this time the expectations towards genre and author won me over and in expectation of some higher quality content I came to accept those other elements.
By accepting this part as totally normal for some unknown reasons, we get some sweet and intimate encounters with the quire and the story keeps going without stalling. A big win I would think.
