For gamers of any variety, this article is a great read. Nominally about the Warhammer 40,000 wargaming community, it’s much more about the consequences of mixmatched expectations of play.
These mismatched expectations led to the effective end of the board game club I used to organize, and they were a major component in the end of my torrid Netrunner love affair as well.
Thankfully this has been avoided in our Star Wars RPG group without much conscious thought given to it. We all seem to be there for a mix of Narrative and Casual reasons - beating the bad guys is great, but having a laugh about the attempt is even better.
Anyway, enough rambling from me. This is a great article - go read it.
