Personally it's not so much about "long-term play" (I had at least two BECMI campaigns go to 36th level); although I can see why a wider variety of content, be it spells, classes, monsters, races, etc. may increase long-term replayability, what I am mainly after is ready-made content I can drop into a game with the least amount of work. Just looking at the pages describing Sages in the DMG is an eye-opener: coming up with that stuff takes work, a LOT of work. When I was a teenager or in my early twenties, I had a lot more time; nowadays between wife, kids, and work, I consider myself lucky if I can put together one or two games per month. So any help, from the least amount of sources as possible, is a no-brainer.B/X Blackrazor, despite his name, has gone all-in for 1e, for the same reasons. He asserts that AD&D has the best rules for long-term play.
Curiously, one way in which I have "advanced" my B/X (for when I don't care about a lot of detail, but I still want something "more"), rather than going the BECMI route, is using select bits from OD&D's Greyhawk:
- Separate (more or less) race from class, with exactly the same class and level limits in Greyhawk (including half-elves)
- Tweak the classes per Greyhawk: increased backstabs for thieves, sweeping and exceptional strength for fighters, intelligence table for magic-users, paladins
- Tweak the races per Greyhawk: elves and dwarves get some boons (elves can hide like halflings, +1 to hit with sword and bow; dwarves get AC bonus against giants, +1 to hit giant-class; all races get race-specific thief bonuses.)
