Why YSK
One Of Lemmy’s creators mentioned it as part of the inspiration for the name, so it’s a nice dive to play the game.
Per Wikipedia
In a 2020 post, Lemmy’s co-creator Dessalines wrote about the origin of the name Lemmy. “It was nameless for a long time, but I wanted to keep with the fediverse tradition of naming projects after animals. I was playing that old-school game Lemmings, and Lemmy (from Motorhead) had passed away that week, and we held a few polls for names, and I went with that.”
Because of that early shockumentary, the idea of lemmings jumping off the ledge is now permanently lodged into the hive mind of humanity. So much so, that there are several games about it. The ramifications will probably continue to ripple through society in the coming decades.
