I could see that. Do people really have an agenda driven toward RPG's with deliberately or explicitly gamelike elements?
Well, yes, but maybe not as you stated it. I'll try to explain what I mean, while avoiding Forgisms as much as possible.
Imagine a person who likes to play chess. When that person sits down at a chess board, they have a plan or goal - an agenda: to have fun playing a game of chess. They are not trying to simulate anything. They are not interested in dramatic narrative. They just want to play a game - they have a gamist agenda.
Now, imagine a gamer who really likes the tactical wargame aspect of D&D. A player who loves working on optimizations, who likes playing with the fiddly-bit rules at runtime - the player for whom this sort of rules-focused activity is a form of play they actively enjoy. When this player sets down at the table, he or she is not really worried about the plot of the session, or whether there's a reasonable monster ecology - the player is there to get to the fight scenes and kick some monsters around.
This player isn't much different form the chess player - there to play the combat game - and has a gamist agenda.
In general, that thing that you want to do when you sit down at the table, that's your agenda.
