Development

Each region has a Settlement Level, determined by the number and level of Burgage Plots. All regions start at settlement level 1: Small Village.
 * Level 2 (Small Village) requires 5 Burgage Plots of level 1.
 * Level 3 (Medium Village) requires 5 Burgage Plots of level 1 and 2 Burgage Plots of level 2.
 * Level 4 (Large Village) requires 10 Burgage Plots of level 1 and 5 Burgage Plots of level 2.

Each time a region increases its Settlement Level it grants a Development Point, which can be used to unlock new buildings or upgrades or make existing ones more efficient. There are 4 development trees, each one with 10 or 11 development branches.
