On multiple occasions.
In fact, my Infinite Weirdos campaign (catch up
here, link to Denver
GURPS forums, same place tshiggins' Facets game is archived; mildly NSFW for offensive language), is another culmination of several story lines from different games with different players over several years. It, like many of my games, ties back into a “pre-historic”
BattleTech game that we played in High School (in pre-historic times, which concluded with the "Battle of the Gates of Dawn"). It also has ties to GummiBear’s MegaDenver game and events that occurred in it, leading up to the previous multi-thread event which culminated at “The Battle of the School” and a major battle in the war for the multiverse.
Only Hand of Bobb gets the majority of references and understands what is going on, but the other players are gathering information and realizing there is so much more going on.
But, at the end of the day, all they really care about, right now, is what happened to Sherry.
