@Jennkryst Yeah – those games were all before Nemesis was released, and chose to ignore it and part ways with the canon timeline.
There was one good thing about the time-travelling murder hobos, which is that everyone OOCly knew their secret, since logs of their actions were shared on the game wiki. Contrary to the arguments of OOC masq proponents about how impossible this is, the players kept it OOC knowledge. Some managed to figure it out IC in purely IC ways. Many players thought it was pretty shite game-writing to restrict knowledge of and action regarding a universal threat to a small group of PCs, and had no desire to support or cooperate with that element of the plot, but still I have no recollection of cheating being a problem.
