No matter how well your Game Master runs games, be it roleplaying or wargaming, sometimes she will need a break.
Step up. Run your own scenario, short campaign, or that published adventure everybody’s talking about.
Let your GM have time to think of something new.
Let your GM’s batteries recharge.
Let your GM be a player for once.
Who knows? Maybe your GM might see certain problems in a different light on the player’s side of the GM’s screen.
