So maybe this turning into a dead horse but a few things have gotten me thinking again. There’s plenty about both that should be cross pollinating. Let’s get the great big game mechanics elephant out of the way. They are two different game styles and rules but still close enough that many concepts and adventures can cross over. Heck, I ran Death Frost Doom for 5E and converted it on the fly. And the Advantage/Disadvantage mechanic, I think most folks think it’s a pretty good idea. So there’s that.
5 E has put D&D back into the mainstream spotlight again and not in a Satanic Panic sort of way. So that’s good for everybody. More fans means more folks who might wander from 5e over to other games. Be they OSR or even other things like Savage Worlds, d6 or whatever. But there’s a good chance if they’re D&D fan the OSR stuff just might have some allure.
On the flip side, I’ve way too many youtube videos (too many to mention here just google in on your own) about how DM, how to make adventures and so on. You know things that the old hats have been talking about literally for decades. More often than not I say to myself, “Isn’t that just like an article or blog post that I read years ago?” What a lot us old grognards have is experience. And you should know better than to be a jerk about it. (Since this on the Internet I need to throw in silly disclaimers like that now and then.) Crap. The whole OSR thing grew because of sharing ideas.
Oh yeah. And one final thought about RPG Communities. The most important RPG Community is the people around your table.
