It's kind of cool when board games are abstractions of real world patterns. It's like you learn something about the world, about how it _really_ works, when you play. Monopoly (capitalism) or Diplomacy (international relations) are probably the most famous examples, but I'm sure there are so many more out there like this one on language that I've never heard of.
Game looks pretty cool
Okay, it sounds like it really affected the author or whatever. But I still have no idea what the game is actually about after reading this.
The funding page has more information. Players follow a scenario and create/are given a vocabulary. The meaning of each word specific to each player, creating dialects among the participants and exploring how language evolves over time.
