We can’t really call D&D Fifth Edition “old-school” since, you know, it just came out. But it appeals to some of those sensibilities in a way the previous edition did not. With that in mind, I’d like to run some adventures from Dyson’s Dodecahedron in 5e. I have a LFG ad on Roll20 for Tuesday evening. If the experiment goes well, I will run some more later, perhaps as sort of an open table.
In addition, hopefully those of us who enjoy this style and gel together can use this as a stepping-stone to a real campaign. One-shot adventures seem like a good way to find players – and for players to try out a GM before decided whether they like the GM’s style.
