UHVs which states that you should "Control" certain areas have become much harder (and in some cases impossible) with the new larger map.
It is not the conquering part that much harder, it is the amount of cities you need to own yourself to control the area.
Having that many cities which are required will cripple your economy, making other science based goals impossible in combination.
Here are some proposals which can make these goals easier. I know some of these proposals are controversial with the parts of the community here, but atleast pick one!
- Rework AI to settle cities further apart. Also pre-built cities needs to the further apart.
- Modify the cost of having many cities so that is scales slower with the amount.
- Change the UHVs to allow vassals to be part of controlling the area.
- Remove the raze city penalty.
