Thom, cause this is very loosely based on measurement, remember when I wasn’t 250 clams behind you, and 2,000 seemed like a reasonable goal to achieve by CotC. Ah, those were the days. If I remember correctly there was even a time about 1,000 clams ago that I was the top Oithling. Good times
While “Yort” is funny and theme-rich it’s not a good idea for a game’s terminology. In general, trying to implement non-ubiquitous units of measure in a game is an exercise in frustration.
For flavour text it’s fine to use something like yorts but for anything where players are required to make a mechanical judgment call based on a unit of measure it’s unwise to use a made-up unit. Measure distances in feet and yards, measure time in seconds in hours, measure weight in pounds, etc. Also, just assume seven-day weeks with the days-of-the-week that everyone knows. It’s just less confusing that way.
