My goal with most (but not all) of my content is that it should be compatible with every edition of D&D.
My content can be broadly seperated into three categories:
the two editions of DiceDream, my home system -- which can run any D&D module from any editionrules variants classes
I have organized my content into that respective order
I am currently hosting this: https://itch. Because they satisfy this restriction, they also end up being compatible with many many other games that are similar to one or another edition of D&D.
