I like the second safe house and the training one.
I will be adding much more to that mod for later eras. There will be a National Security Service with two possible branches Internal and External based on the number of cities you have. These cost a lot but open up more missions and the like.
I want to get the police part done next so that we can replace/implement Scotland Yard properly. There will be:-
- Village Police Station
- Town Police Station
- City Police Force
- Metropolitan Police Force
- National Police (Scotland Yard, FBI(?), AFP etc.)
- InterPol - don't know how to implement that one
Each will upgrade to the next one up and require the Administration building of the same name. City Police Force will also require a courthouse. There will be a few lockups of varying sizes for people awaiting justice.
