I didn't expect the board game genre to remind me of the RPG groups, but it does. I joined a group that meets once a week and while for me it is more like a social event, for them it is social and a serious hobby. They buy games, trade them, get upset when they lose, don't like playing certain games with certain people or expect people to play the game in a certain way. It is really very much like a rpg gaming group.
that I envisioned playing a few hours, then suspending play until next session, etc. Plus, if a character dies, a new character is assumed by the player, giving the game a pseudo-RPG feel.
