Thanks for your reply. I haven’t actually played for a while, since about 2013, but at that time I did adapt a lot of Codex Martialis to our game. We played a mix of AD&D 1st Ed. (with some 2nd Ed added) and Chivalry & Sorcery 2nd Ed. Essentially, character creation and abilities from AD&D, combat a mix of AD&D and C&S, magic as C&S (with lots of house rules) but mostly AD&D spell lists. We always played a Greyhawk campaign, regardless of how many times we changed or adapted rules, LOL. Not the high-fantasy high-magic usual campaign, but a more low-magic one.
I have been slowly rewriting all the rules we used and trying to compile them into a coherent whole set of rules. It’s a hobby project, and takes some time, and I have been mostly trying to decide on formats of spells, and to “fix and define” the final rules for spell-casting etc… I have arrived at a set of rules that are largely inspired by Code Superno, Lion & Dragon and some C&S 2nd ed.
I think Codex Superno is a superb book, one of the more interesting supplements having come out these last 2-3 years. For what it sets out to do, it is pretty much perfect. Congrats.
