Reforms

[The Wandering Scholar]

How come for polybian to marian you have to destroy but not for the others?

[blacksnail]

The short version is that Camillan to Polybian and Marian to Augustan represent the gradual shifts over time rather than any specific centralized reforms. The shift from Polybian to Marian represents the fairly rapid transformation of the Romani legions as instigated by Marius.

So how come there has to be this mass destruction?

[MarcusAureliusAntoninus]

Only 9 buildings in a building tier. So, you can fit the Camilian and Polybian in the same building tier, but the Marian and Augustan have their own building tier. Since you can't upgrade from one group to a different group, the MICs have to be replaced by the script.

Short answer: hardcoding.

Because RTW won't let us destroy a building by script. IE, hardcoding.

I had the Polybian Reforms, but in Arretium, where I built the highest tier MIC before the reform, the upgrading doesn't work. I can still only build Camillan units there. Even destroying the MIC/government building doesn't change it.

Do I have to wait for Marian to get rid of the Camillans in Arretium? :P

Did you destroy the government building or the barracks(=MIC)? The governement building has nothing to do with it, provided you stick to level 1. Replacing/upgrading the barracks will bring you the new units.

Therefore you shouldn't build the highest barracks in Camillan times.
