I would love to play a retro clone like Old-School Essentials, Labyrinth Lord and Swords & Wizardry. I wanted to try the old school DnD mega dungeon system.
For non-Dnd system I would like to Apocalypse World system like Monster of the Week. I downloaded a new system called Coyote and Crow that seems very interesting. It is set in a North America that was never colonized with some cool magic elements. The setting looks dope but I have no idea about the mechanics. I didn't get that far in my reading of the rules yet
