This is just about the coolest thing a Google search for “d20” could reveal.
I’ve always thought that the games humans have played through the years have had to have been more complicated that Hit the Ball and gambling with d6’s. We tend to tell the story that that’s all there was till Kick the Can and then that’s all there was for another while and then finally someone invented video games or sports, whichever you adhere to. The thing is, humans have got to have been thinking more than that. I’ve always thought that children’s games and sports of the past must have been a lot more like ours than we make it sound, only with less regulations and padding, and that we’ve simply lost these games to time.
Not that the Egyptians were playing their own brush & papyrus RPGs, but then again, they had an elite, developed “first-world” society that may have produced an appetite similar to ours for games. Who knows, it might have even been some kind of word game like Scategories. They were definitely thinking more complexly than d6’s, though.
