You guys saw what we did for the Summer Solstice and that's the kind of system we'll be using for this kind of stuff. The answer's yes, we want to do all kinds of things with it. So, we've built this events system into the game where there are things, events that can happen in the world – whether it's making certain items available at vendors or making certain buildings or NPCs or other types of generators appear that weren't there before, built into the game, and triggerable by season, holiday, time of year, time of day, or manually triggered by us for one particular reason or another.
