I post in the voice of Christopher Walken
If the player (or players) want it one way, the GM wants it another, who gets to decide? I'm perfectly willing to call that the person who "wins" here.
In my view this is the wrong way to look at such a social situation. If you are thinking in terms of winning or losing, that is a recipe for problems IMO
But again, this is an all-or-nothing view. Its entirely possible that parts of the game make them happy and parts very much not, and they have to decide whether they're willing to sacrifice the former for the latter.
Like I said before, as a GM, I adapt to the group I have. I have no problem with adapting. But I am also not the players employee or mule. When it starts to become about players wanting a very specific kind of game, and it feels too difficult to accommodate, or it interrupts the enjoyment of other players, I think it is clear that player might be better served with another GM. This is a street that goes two ways. Yes the GM will bend to certain things, but the GM has to also account for the other players at the table and the GM's own capabilities and style (there may be a style of play you want me to introduce that is perfectly reasonable, but it simply isn't a style i am comfortable running). But players also have to adapt to the GM. If I am in the shoes of the player you are describing: one who likes some elements but not others, I am not going to bother the GM or group with that. I don't want to make demands on them that they change to fit my very particular set of interests here. I wouldn't mind making a soft suggestion (such as, how do you feel about this sort of thing in games). I just don't think it is good form to cramp someone's' style or treat it like you are ordering something at a restaurant.
