Settlements Start at Tier IV
This mod makes every settlement on the map start at tier 4, with all secondary buildings upgraded to max level. It also gives a bit of bonus income, scaled by difficulty, to both the player and the AI to allow them to make use of all these slots.
This effectively lets you skip a lot of the early part of the game to immediately begin recruiting most units.
I wouldn’t recommend playing as Daniel with this enabled, unless you like pain.
