Which is probably exactly what Retreater needs. Which is why he should do it.The problem I've found with that is the longer gap you leave, the more likely people get out of the habit and may even end up committing the time frame you want with something else.
If the players all find something else to do with their time, then they truly didn't need Retreater to kill himself for them and he's now much better off. But if they all hang around and want to play again in 4 months time... he at least can say "Well, if you want me back, then we're doing things my way from now on. Otherwise, someone else can run this stuff."
