This is not a game about middle age, and never will be. The settings are different, the history is different.
There are things possibly borrowed from our ancient history, but they must have their own development.
An artisan could surely be wealthier than a warrior in backgrounds like Yliakum
The realism I'm talking about, it's obviously proportionate to the settings of this game in particular, and every RPG needs flexible logic to be playable, being D&D, GURPS or whatever.
Edit: when, in a far future, my grandchildren will see the Version 1.0.0

the game will be different from now, and so the gameplay and expanded backgrounds. For me that's a thrilling reason to stay here and participate, one step at a time.
