I was just reading some tech stuff in a ‘speeding up Counterfeit Monkey’ topic from a few years ago (Testing Counterfeit Monkey on Iphone?).
It points out that in the standard rules, a default state for a thing is that it’s mentioned:
A thing can be mentioned or unmentioned. A thing is usually mentioned.
Then when the game starts up it does this:
This is the declare everything initially unmentioned rule: repeat with item running through things: now the item is not mentioned.
What’s the reason for doing things this way instead of making everything not mentioned by default?
