so Makanyane is right: I'm sure this comes as a surprise to none of us.
Yo, print and frame that comment! Unfortunately I was only right after being completely wrong on my first post!!

Monkwarrior thanks for testing that out, assume we now know reform requires last govenors building, to make huge_city in region with 'italy' resource. Only variable I'm not sure we pinned down is if roman faction has to occupy region. Did you work that out in your testing?

I've had some bad experiences using "building_present_min_level" on the "recruit" line. I've decided it's safer to use it (as the vanilla game does) as a precondition for a building upgrade. Am I being too conservative about this?
No, there are some major flaws with using building conditional on recruit line in later RTW versions ( I think it used to work for 1.2 but doesn't for later), 1, visual only - the requires building bit appears on unit recruitment line in campaign. 2, if you apply it to buildings that have already have a bonus - like stage_races for hippodromes then you get a CTD when you view building in buildings list.

there are some others I don't entirely remember but I think there's a limit to the number of units in a building that can have conditional - and in some circumstances right clicking for unit info on a unit that has a building conditional will also cause CTD.
