Given that WOTC released the SRD 5.1 in two versions last year -- an old OGL version and a new Creative Commons (CC-BY-4.0) version (download link for the pdf of CC version: https://media.wizards.com/2023/download ... C_v5.1.pdf) many (if not most) D&D terms are available for use in CC-licensed games. All you have to do is give an attribution to the SRD-5.1 in your work as the Creative Commons license requires.

I will eventually release a version of Microlite74 under CC-BY-SA using the CC versions of the SRD 5.1 and Basic Fantasy 4th Edition as the basis. This will be the "simple" versions of M74 only (conversions of Microlite74 Basic and Standard). I lack the time (and frankly the interest) to do this for all the longer, more complete versions. Very few changes will really be legally required for these simple versions, however, some changes will be made to "improve" things a bit (like replacing the term "race" with something like "ancestry" or "culture") for this 4th edition of M74. I'm also going to write my own intro paragraph giving that many of the people downloading M74 these days have little or no idea what Microlite20 is -- so the current intro paragraph carries little meaning to them.

I will try to get this into the library soon.
