Yeah, world-building in such a short timespan is a bit crazy. It's part of the reason why I decided to choose a more enclosed environment, where the worldbuilding is much simpler and I don't have to go into tremendous amounts of detail, but I guess some of us probably had story ideas that we'd thought of with fully-formed worlds that wouldn't need much more in the way of worldbuilding. I still think it's fun, trying to worldbuild on the fly, but that's probably because I've got the kind of story that doesn't need excessive worldbuilding. I can't imagine trying to go for the kingdom building theme would be fun though - that'd require so much worldbuilding in an incredibly short time period that I really wouldn't know where to start.
