No flips for you!
That you cannot see the negotiation inherent in this, or that you don't see the negotiation that takes place during your game (the negotiation of action declarations attempting to achieve a specific goal and your, as GM, preferences for outcomes) is the reason so many recent discussions have been a challenge with you.It may be important but that doesn't make it not obvious. On board game night when we all decide on Settlers of Cataan instead of Ticket to Ride, a negotiation has occurred. So some sort of negotiation is true of all games involving 2 or more people.
What may not be obvious is roleplaying games are not just one game. That beyond choosing D&D perhaps you should also decide on the style of game. In my case though there really isn't much of a negotiation. I announce I have a campaign ready to go in my preferred style and ask who is interested. Those who are join my game and those who are not do not. I'd even go so far as to add that the beyond the game, and the style, there is also the theme of the world. So I might have a player want to play one themed game but not another. But there really isn't much negotiation going on. It's take it or leave it.
