There's something about me that a lot of my players can't grok. I don't know if anyone else feels this way—particularly other DMs. It's something deeply ingrained in my play style. That is, if a game goes unplayed for an extended period of time (usually around a month), I lose all desire to play it in the future, possibly for all time. My notes still exist: I just have trouble interpreting them. All the thoughts that were at the forefront of my mind as to how this party is going to handle x, y, and z, or what their plans, fears, and thoughts are, all of that erodes over time and dissipates into strands of morning mist. In a sense, the campaign deconstructs itself.
I've tried to explain this several times, but its always to an audience that can understand but not appreciate the feeling. They grasp the idea that I would feel this way, but they are unable to completely interpenetrate it with their thoughts. This leads me to believe that my own predilection for abandoning games is rare or possibly unique in the world of roleplaying. They have all expressed a profound regret at characters who are never officially retired or killed in any capacity. They feel a lack of closure in a sense. I don't ever feel that about abandoned games. Instead, I feel that they are narratively closed somehow. In the same sort of way that Sartre talks about all potential futures becoming an accretion of already-realized pasts, this is what I feel like abandoned games become. Their futures have spun out already, have been drained of possibility, resulting in the calcified now.
Are there others out there who've experienced this? Is it a private insanity? Perhaps it's something DMs feel more than players do. I don't know the answers. That's why I appeal to you.
