Frankly, I’d really like to play D&D 5e, but I can’t get anyone else to DM. Same for Call of Cthulhu 7e.

As far as systems I haven’t run before, I’m interested to see what MCDM’s system turns out to be.

Stars without Numbers seems cool (though I do prefer a system that lets me use dice I can’t find in a Monopoly box).

I own, but have not played (player or GM) the Avatar Legends system. It looks very lovingly put together, but I wish it hadn’t been built on Fate.

I’ve also got a neat little indie(?) system called Upwind that is very narrative focused, and has players sort of bet on suggested conflict outcomes against the GM with a hand of cards. Very interesting, but I haven’t had the bandwidth to get ready to run it for anyone.
