Return to Nib’s Knoll (2014) (aeon.co)

Author is offering $1k to find his creation on MicroMuse.

It's a good story.

I remember back then the atmosphere was of extreme politeness... crazy how times have changed

I think he's correct that Minecraft scratches much of the same itches that MOOs scratch(ed). It's a little sad: at least some of the creations built as MOOs are still around, but will there be any Minecraft servers left in 30 years, and if so will any of them have builds from today on them?
