Editing Basic Dungeons & Dragons (section)

===The Adventures===
Frontloaded. The B series got at least 12 of these in the end (including one that semi-compiled the first 9 into one adventure). The X series of adventures had up to 13. By contrast CM went only to 9, and M got 5 (most of those were awful). Immortals had 3 modules (did anyone even play those?).

There was another M line, for single-player us in the Basic tier called MSOL (Mystara Solo). Also an O line for one-on-one between the DM and player set for expert level play. The DA series for [[Blackmoor]], also expert level play, and was four modules.

Usually the rule was, "if you're going to include Companion Set shit in your Expert module, list out the vital-statistics in an appendix." It was ''usually'' followed, including in the supposedly-expert DA series. [[X4-5-10: Desert Nomads series|Dobson's X10 warfest]] broke that rule, but hard.

Basically most players didn't get their characters far past level 8, before just switching to AD&D, and TSR catered to that reality. That said, a lot of modules people remember most fondly of 80s D&D were meant for this line, many of them have been mentioned on this page already.
