I just stumbled upon Marc Jacobs and his Foundational Principles for Camelot Unchained, through this post by Bhagpuss.
Once upon a time when I was playing WoW, a guild advertisement popped up in the trade chat. The newly made guild would only accept “the coolest, most leet and hardcore players”. The ad also explicitly mentioned “balls of steel”, possibly in the guild name itself, I don’t quite remember. Or was it iron? Some metal alloy, for sure.
The lifespan of the advertisement campaign was one day, maybe two, they were laughed at so hard. So why did I suddenly remember this while reading CU’s foundational principles? No idea, must be a total coincidence.
