If I believe in the theory of game styles...

does that mean that people bringing different styles of play to the table will have expectations that don't match? If expectations don't match then I would expect that problems could occur. Maybe people wouldn't get into it if the style was wrong. I thought maybe I might list the people I have gamed with and then what style I would assign them.

Gamist - Goal orientated
Narrativist - Story focussed
Simulationist - Realism focussed

I decided to go with what was floating around rather than use the names I invented (The 3 Rs) because I had another look and they were basically the same.
