A.k.a. "Bitcon"; the underlying theme was "Save someone else's world" -- PCs were visitors to Mythlaya and could go back home to a safe place between scenarios. The decision that there should be one "bit" per run, with each GM taking one major "bit" and several minor ones, meant that we had something like 43 "bits" to fix, most of which were nothing more than minor quality of life issues. This was the year that gave us the Bob West Color Chart -- twenty pages of what happens to every named color on an artist's palette when the underlying color wheel rotates 120 degrees. This was one of the "bits", although it had three settings instead of two. It also made the players really motivated to fix things when they discovered that Caucasian skin tones were "Smurf blue" in Mythlaya.
York Dobyns recalls: Oddly, I can remember that one of my minor bits was a screwy problem with friction (which led to rock-skiing ogres), but can't for the life of me remember my major bit or climactic scenario. It's all in my old Princecon papers ... somewhere.
Bob West recalls: This was the year of the "miracle", where the "there is no sun" bit was flipped just after a lich in my scenario (who could be out of doors) had cast a Concentrate on himself, and got all four surviving PC's to fail their saves against the same Hold Person. He was about to slit the PC's throats, when Winston came in with a paper announcing that the relevant bit had flipped. I rolled for time of day (publicly) and got 12 noon. The lich looked up, cursed, and was dispelled.
Hugh Huntzinger recalls: there were also some "Lords" as special NPC's joining the PC's on expeditions, who gained levels as bits got flipped (restored). There was also an 'Alchemist' NPC class that was being experimented with as a PC.
