I have some experience with 5e (currently playing an online campaign), Shadowdark and also played quite a bit of Basic Fantasy RPG solo. I would love to play some OSR game (ideally Basic Fantasy or Shadowdark, which I have some experience with), but I wouldn't be completely opposed to another system if you really like it and can convince me
I have never been a GM but would like to try it at some point. I think I still need more experience to be a good GM, but if no volunteers appear, I could give it a try
I hope we can play some fun campaign!
