Castle taxation?

[Malachus]

Is it possible to change the tax income for castles to be variable like that of cities or is this a hardcoded feature?

[SilentResident]

Its hardcoded. Castles & Citadels are only "militaristic" settlements.

What do you mean with variable tax income?

[Malachus]

Variation with regards to low, normal, high, and very high.

[alpaca]

Ah, then it's probably hardcoded indeed, as SilentResident wrote.
