One of the things that happens in gaming groups that play rpgs is that players and the GM may want to play different systems at different times. This is balanced out by the desire on the part of players (and GMs) to play long-term campaigns (lasting more than six months of real time, and sometimes going for years) of one system.
My question is: How do folks balance out the desire to play different game systems with the notion of playing one rpg for a long-term period of time?
And what is the longest running campaign of an rpg that you've run, and what game was it?
Okay, that was two questions. :)
