As someone who is trying to dip my toe into OSR gaming right now, I have been having quite a few conversations online about the style of play and the general community that surrounds that style of play.
While doing my research and prep I have observed what I think is a disconnect between what many think OSR is (or should be) vs a modern 5e system. So what does OSR mean? OSR is Old School Revival (or Renaissance) which bases the D&D game on the early D&D editions. I have spent quite a bit of time over on r/OSR and on Discord to facilitate my discussions on how to structure a game. I came into this process thinking that OSR = Rules Lite = narrative forward design. Many of the OSR systems I have seen tend to pull back a lot of the rules and complexity that modern 5e has. I think the assumption that OSR is narrative focused is incorrect based upon the feedback I hear from the community. Ironically, it almost seems like the OSR community wants more tactical, more grit, more number crunching for battle with out-of-encounter RP to get out of the way. That seems counterintuitive to me when you are pulling away the more complex math and skills you might find in PF2e for example.
I wanted to take a break from 5e with my group because I feel like I am getting burned out on the load of prep that is expected of the DM. Im spending hours each week to prepare maps, NPC's, encounters, etc and my players just roll up to the table. Now my group is pretty evenly split on the role-play vs tactical battle divide of how they play 5e.
