Is Imperialism in Rise of Rome bugged?

[Fistleaf]

There appears to be no support costs although there is a free support number on the military advisor screen and in the civilopedia. Makes this government very powerful.

I don't know if this is incidentaly, because it has some sense. Imperialism is a must go at this scenario

I think it's ok. No bug to me.

Imperalism is supposed to be a game winner in Rise of Rome and is located in the right spot on the tree.

BTW, in Fall of Rome, all barb civs start in a govt with free unit support, and Rome is still in Imperalism, which is very awful in that conquest.
