I personally believe that adding an STW style trading/income system will work best and the AI will be able to hande it without much issue. The vanilla game falls down because adding the principle source of income to only a single building means that when the province is invaded that source of income invariably get's razed automatically or in the case of trade gets cut off by the random nature of shipping lanes... If there are more than one income generating buildings in a province then this is less likely to happen. I would have income coming from the following:

Farmland upgrades
Mines
Ports
Traders
Churches
Cathedral
Mosques
Grand Mosque

It does not have to be a huge amount of income, but a reasonable amount per structure.

Well I don't buy PC's, I've always built my own - but I do usually have a second PC hanging around. At present I do have one, but it also needs a graphics card - and anyway I do not want to have to run two PCs.
