Once you’ve created an interesting world for you tabletop game, the next step is to fill it with stuff that is either currently happening, about to happen, or has happened. You really only need one to have one built out, since the others tend to grow out of exploring one, but it doesn’t hurt to have a few different options of each kind so you can run the game your players are interested in playing. You could try to predict that ahead of time and build the precise number of interesting things you need in that direction to make the world feel lived-in, but it’s usually more fun if you have a bit of each. In my experience, it always feels rewarding when the players find ties to past events that get them excited to learn more about whatever situation they’re in, when players can tie current events to past events when they initially seemed unrelated, and everyone loves a bit of foreshadowing that pays out.
