Speaking of moving on – do you ever run long extended campaigns?  I used to have this desire to run different games but in the last several years I’ve found myself far more content to stick with a given game (assuming everyone is enjoying it) and just stick with it. 

One shots aside I want to see where a game/players go as things progress and escalate.  I think that in some games as power scales up and the game broadens even if the core mechanics don’t change the game often has.
