From The DM (11/29): Winter is coming? How to make tracking seasons fun.
When was the last time it snowed in your game? When will winter come? What season is it now? Summer? Still? Wasn’t it summer when everyone started at 1st level? Did everyone really gain ten levels in the space of one season? Does this world even have any seasons? Just what the hell is going on?
The weather can be a surprisingly slippery rabbit hole for the unwary DM. Around this time of year, as the weather starts to change out there in the “real” world, players are particularly likely to start asking tricky questions.
It’s the little things that make a game great.
