The rule could be anything, as funny or as serious as you want. The universe will progress in a similar way that it has up until this point, unless your changed rule prevented it from doing so.
Some examples might be:
- The invention of currency is not allowed.
- Iron is slightly less stable.
- The Ancient Greeks are able to cultivate Silphium, which does not go extinct now.
I’d eliminate the Joestar bloodline.
Would you also reject your humanity?
No, I’d try to achieve heaven
But without a Joestar to do it for you, could you handle the Pillar Men yourself? 🤔
Yeah, they wont see what hit them (literally)
