There was a thread (
@overgeeked maybe?) talking about running multiple editions at the same time. A better DM than me, but regardless a ToV Halfling vs a 2024 Halfling, vs a LU Halfling...yeah sure you could do it....but why?
I get the appeal of having all the other branches discussed in the main branch, most everyone wants to be included in the main branch of discussion as it gets the most eyes.
I do wonder however if we are not doing ourselves as a community a disservice, by not just splitting off and building these other games up, instead of continuing to discuss them in relation to the main branch, which for many of us now is irrelevant as a core rule set.
