can't say how up-to-date this collection is, but there's a About Plurals By Plurals collection over on itch.io!
every game/story I've experienced from it has been excellent, but I'll shoutout I Am Dog(s) for being the one that made me go "whoa, Twine is great for plural storytelling, actually?" and got me looking into how it all even works; and driftself for beautifully illustrating alienation, race, and fucked-up personal history.
