By the way, I was checking up on Outlands material in 2e products. Removing 2e-specific material, the original box set has 30 pages on the Outlands, and the Player's Primer to the Outlands had 25, with much the later's info just repeating from the first (as it was player-facing and not DM-facing as in the box set), compared to 36 here. Only 7 of the 16 gate towns got coverage in the box set, and while all 16 did get coverage in the Primer, they were all less than a page, compared to 2 pages each here. And that is all with the Planescape line's much larger font and with quotes and art taking up huge swathes of page space, both of which much more than 5e does. The only place the 2e products come out ahead is with the godly realms, with both 2e products having 5 (mostly repeated) pages to the 5e's 2.
