“Roll20” doesn’t refer to a d20 mechanic, it’s an online platform for playing games. The site we used along with Google Hangouts in Cute Boys Holding Hands.
If you want some fun and crazy times: Fiasco.
If you want to try something hard: Jay Treat’s Strange Gravity.
Those games’ll change things around and quick.
I really wish Daniel hadn’t taken down the free artless version he used to have on DriveThru.
I downloaded a copy when he had it, but I should buy the actual book sometime. It’s bizarre and I love it. I wish the initiative system was easier to emulate online, though…
The King is Dead is still one of my all time favorite games. Dialect as mentioned by the great @yoshi is another killer game.
