I keep hoping we will get an updated version of Planescape. You’d think the attention @HollyConrad has brought to the setting would have pushed it more to the forefront. Guess I will have to keep on dreaming. We love Planescape! That's why chapter 2 of the "Dungeon Master's Guide" is drenched with it.
