In 1975 a group of Caltech students published Warlock, one of the first supplements for OD&D. Holmes used this system for his personal OD&D games prior to editing the Basic Set. He was a fan of the Warlock spell point system and mentioned in Dragon #52 that he tried to get Gary to include a spell point system in the Basic Set. I've written up a summary of these rules if you are interested in trying them out, either in your OD&D game (particularly now the pdfs are publicly available) or in your OSR game.

Mike Mornard on M.A.R. Barker's immense Tekumel/Empire of the Petal Throne megadungeon:
"One of the tools placed at our disposal was the underworld that [Barker] had placed under his starting city, Jakalla. I had explored parts of this, but had never seen the entire map until now. Phil used a 17 x 22 sheet of TEN SQUARE TO THE INCH graph paper, with each square equaling ten feet (just like in original D&D). Think about it… that is enormous. Over a quarter mile on the short side, and nearly half a mile on the long side, and all of it full to the brim with interesting stuff and horrible doom. For instance, in the southwest sector is a maze. And when I say a maze, I mean a TRUE maze; one way in, one way out, false turnings, dead ends, the whole nine yards. It’s about 900 by 900 feet. That’s three football fields."
