Surely everyone posting here is already playing a game. If you just wanted information about escorts, you can read threads and reviews without being an active member. Once you start posting, you are part of the great UKP game.
You'll see plenty of examples of gamesmanship here- people boasting about their punting exploits and trying to do one better, coming up with challenges, working through hitlists, slagging each other off etc etc.
I bet if you went to a forum about an actual game you would see similar patterns and behaviour there.
