There are various differences, but they are basically minute when it comes to these types of AVNs, even with sharing which are technically the real cuckolds they can do it for multiple different reasons, some are into the hippy free love kind of thing while others want to feel humiliation, but you typically only see one type of that in these "games".
In AVNs, 99% of ntr is cuckoldry on the basis of humiliation, it's not purely that the mc is down of his luck and gets cheated on or whatever, nah they make a point of humiliation and people get off on that. It's a humiliation kink.
I disagree that choosing to be cucked is wholesome

we'll have to agree to disagree on that.
Seems like my comment struck a nerve, I genuinely don't get it. If you like cuck content, then good for you, I just don't see why you're so defensive about something you enjoy.
