From Bifrost, an exceedingly rare RPG from the 70s. The rules require (well, strongly encourage) alcohol at the table, but warn against playing when you’re too drunk to read your dice.
@jameswallis I got the pic from the Mesmerized By Sirens blog, which is devoted to very early rpgs. The author is very excited about the possibility of bringing it back. http://mesmerizedbysirens.blogspot.com/2017/12/bifrost-skytrex-1977-resurrected.html
@edheil It's before my time, but I'm pretty sure it was one of those games that people made because they couldn't find an actual copy of D&D, and sort-of reverse engineered it. My memory is that it was a mess.
@edheil Wow, I used to have two of the Bifrost books. It seemed unplayable as written.
