favorite ttrpg ive personally played probably has to be eureka! the fact that it encourages having players leave the room/call/etc when their characters arent in a scene is helpful for me, as a person who can struggle to stay focused for long periods of time- and it just makes for more fun roleplay, when i know exactly as much as my character knows.

id really like to try cyberpunk 2020 someday, though. ive had the book for ages.
