Whereas Previous College Necessities is the most well-liked early D&D clone lately, I favor Primary Fantasy for the refined modernisations like ascending AC.
Only for the report, OSE does embody AAC too — it is “elective” however is included in each stat block, each itemizing of armor, and many others. Character sheets can be found for each DAC and AAC. It is ambidextrous. There could also be different “modernisations” in BFRPG (it has been some time since I learn it) that are not in OSE, however implying OSE lacks AAC shouldn’t be fairly proper.
That’s a good level. And I do like OSE, the format and format is the perfect I’ve seen.
