Mornington Nomic (a Make-As-You-Play game set on the London Underground) has now been updated to version 5:

Version 5 is mostly a re-arrangement of the rules, which should make them easier to understand.
Version 6 update log
The most notable change is that "enact" and "repeal" have now been removed from the rules entirely.
The second most notable change is that I removed 2 of the rules: one of the rules was redundant, the other one just confused people.
Something else of note is that I removed all references to "amendments of amendments of a rule" — it made sentences long and confusing, and you can easily achieve the same thing without it.
All the other changes are noted in the Errata section.
Version 6 update log
most importantly: I think it's at a point where you can read through the rules once and understand them.
And I think it's also at a point where you can skip the Core rules and still understand basically everything you need to know.
If I'm wrong, and there's anything you're not sure about, please let me know!
Version 6 update log
to be clear: the *words* "enact" and "repeal" have been removed, and replaced with more common words, like "add" and "remove"
