Playing two separate Pathfinder one-on-one campaigns with a friend. One where he's the GM and one where I'm the GM. We used to run a shared campaign with random generation to keep both of us on our toes.

I'm also interested in various other games such as Mutants & Masterminds 3e, Fate Core, Swashbucklers of the Seven Skies and Spirit of the Century.

I sometimes use Mythic, the GM emulator, for solitaire play.
