Hi all, first time posting. I've run RM2 before, but these days typically other games.
I once ran some old school OD&D/AD&D games with the RM1 Arms Law criticals charts, to pretty memorable effect, and it made me consider adding the first edition of Spell law—and possibly even the other RM1 single books from there; as an old school gamer, I like the idea of capturing the feeling of having individual modular RM books slowly coming out and replacing the core AD&D mechanics.
My question is about Spell Law in RM, RM2 and RM2 revised. I have RM2 revised, but I would really like to play from RM1 if I can—is that possible from the revised edition? What are the differences?
my understanding is that Spell Law in RM2 is basically the same as RM1, but with 3 added pages of optional rules. The revised edition has many more pages, but from my internet searches I can't tell if this is just because of layout changes or because the actual content is updated/expanded (or if those expanses are discrete, or edited into the main text).
If I want to run things from the very first edition, but can't find/afford a first edition, should I be looking for an RM2 copy of Spell Law, or will my revised book do the job of providing an 'authentic' text of the original publication?
