Yesterday, we had a guest player at my 3:16 Carnage Amongst The Stars campaign. Naturally, people tried to bring him up to speed with what had happened in previous sessions. The resulting summary was unbelievably bizarre.
There's next to zero planning going in to these sessions, which is a big part of it. 10 to 15 minutes GM prep per session tops, and at least once it didn't even get that (as a player once showed up half an hour early and arrived before I'd put any thought into the session at all). Week after week, it's all almost entirely improvised.
Plus, I've made a few attempts to emulate bits out of Tim O'Brien's Going After Cacciato. Cacciato has served as my primary inspiration. Like 60% Cacciato, 30% Band of Brothers, and 10% all other war movies I've seen. Going After Cacciato, for those unfamiliar with it, is sort of a surrealist take on the Vietnam War, told from the point of view of an unreliable imagination-prone narrator.
So when a crazy idea pops into my head mid-session, I make a point of just going with it, instead of suppressing it (or even asking myself if it's a good idea or not).
It all pretty much made sense while we were playing it, and seemed only a little over-the-top at the time each element was being introduced. I had suspected that the ridiculousness was beginning to accumulate, but trying to summarize all that went before for the benefit of a new player made me kind of cringe. What seemed "a little out there" when take by degrees, ends up being completely bonkers and really hard to swallow when dumped on you all at once.
