Yes, like if the gaming host is trying a new game, but people are getting bored or frustrated with it, the guests might be more inclined to do something else that presented itself, and it would be much better for the host to go along with that in the moment, even if later they felt like the evening hadn't gone well.
But, another twist that's more in line with the original scenarios is that it's the HOST who decides to change the tone of the evening, not the guests. Like everyone is invited for Game Night, but partway through the host is like, "I also wanted do some dancing tonight!" and they put away the board games and start up the music. Or a Game Night kind of slides into just sitting around drinking a lot, which the host seems fine with.
As a guest I feel I don't have much control over what happens, and my only choices are to either go with the flow or say a polite goodnight, if I'm able to leave. And since I don't have my own car, usually I'm dependent on someone else who is either picking me up at a certain time (so I have to wait there anyway), or they're also at the party and probably enjoying the new activity and don't want to leave. So I'm not too thrilled with the party turning from the activity I was prepared for into something else that I probably enjoy even less. But, I don't know if that's just my personal preference, or something that's rude in a larger sense.
