I haven’t seen this mentioned yet, but I feel like a world map is important. It doesn’t have to be a work of art, even a rough sketch of a continent shape with a couple landmarks and a You Are Here sign will do. For me, being able to visualize a map of the world and my character’s position on it helps me place my character in the context of the world. This is doubly true if your campaign has a lot of travel, as many do.
This article misses the point. The reason there are no good billionaires isn’t that they change their politics and morality to whatever drives profits. It’s because they have amassed more wealth than they can ever possibly need, while others suffer and die who could be saved by that wealth. If you have billions of dollars that you could have given to the needy and instead you’re sitting on your hoard like a fucking dragon, you have failed morally. tldr: billionaires are dragons and we need more dragonslayers
