I'm part of the Neohabitat project, started by the creators of Habitat and dedicated to bringing it back to life. We've got the original launch world back up and running (over 5000 regions!), and you can play it directly in the browser over at our exhibit site:
See y'all in world!

People did. We were not 100% rigorous in following our own rule. It turned out that there were a few features whose implementation was greatly eased by breaking the rule in situations where, in our judgment, the consequences would not be material if some people "cheated" by hacking their own systems. Darned if some people didn't hack their systems to cheat in exactly these ways.”
Already landing on the "whale" method so familiar in games today. Sadly Habitat didn't have the benefit of microtransactions to break through the pesky limit of minutes in a day to really take advantage of this phenomenon.
The entire paper is a gem; worth checking it out. It has aged wonderfully well, and I never get tired of re-reading it over the years.
He summarized how some of the lessons learned from Habitat applied to StackOverflow/StackExchange, or had to be relearned.
I got to play with it, it's cool.
