I played Dark Sun as a player once in 2000 in university. I then DMed quite a few Dark Sun campaigns using dnd 3.5, dungeon world, FATE, world of darkness, and Genesys. This year will be my first time DMing 5e, and I am going back to Dark Sun. I cannot wait. I personally prefer level-less systems, but my group doesn’t mind as a whole and are quite familiar with 5e so we are going to give it a try. I live in China.
