As I mentioned on one blog, I've never thought the Chartmaster stuff was justified. If you look at RM2 in its core form, you're looking at three books. Add in C&T and you have four. That's it. The Companions were ALWAYS optional, and the RM community did itself no favors by acting otherwise. AD&D was 3-4 books (player's handbook, DM's guide, and monster manual, with deities and demigods thrown in for good measure), and don't think for a minute that Gary's system was lighter in tables. He LOVED tables, all the way down to the henchmen table for higher level characters and so on. He just scattered them (almost at random) throughout the books, whereas Arms Law is basically a collection of tables.
