Until there’s an official holiday celebrating time travel (and there probably is one already), I’m sticking with February 2nd, thanks in no small part to Harold Ramis’ classic film.
Here are a few quick ways to incorporate elements from the film and holiday into a Time & Temp game:
Phil–A man stuck in time, doomed to relive the same day over and over and over. In the early stages, if a phenomenon like a time loop can be said to have “early stages,” Phil’s menace rating on the Keeley-Sullivan Temporal Villainy Index is merely 0. He’s a threat to reality by the nature of his existence, but he has no desire nor capability to exasperate that threat. As he is slowly driven mad by his personal time loop (a persistent-benign-subtle anomaly), his destructive behavior increases his TVI rating to 1, because he is now seeking potentially paradoxical results. And towards the end, once he starts taking advantage of the time he has to better himself, his TVI rating becomes a 2 to reflect the fact that he’s now much more capable than the common man.
Punxsutawney Phil–A groundhog actually able to predict the weather with testable accuracy is an interesting case study for how anomalies work. It is clearly a persistent and benign anomaly, as it lasts as long as the groundhog does and does no immediate harm to those who experience it. But the question of whether it is subtle or obvious is a matter of when it occurs, and how accepting the general populace would be of such a phenomenon. In general, when such portents and augury was considered par for the course, the groundhog would probably go unnoticed and, more importantly, the history books would treat it as a local superstition. This would definitely be a subtle anomaly. In more modern times, when such a critter would be tested, year after year, for accuracy, and when the media would blow the story out of proportion as an example of real magic, the anomaly would be an obvious one.
And, of course, there would be times when such a beast would immediately be burned at the stake for witchery, in which case it would be an ephemeral rather than persistent anomaly.
