As part of this mod I am planning on including a miltary outpost building. This would cost tonnes of money, quite a bit of time and would completley kill trade, tax and growth, however it would let you recruit most factional units anywhere. In essence this building will represent all the tedious micromanagment of moving men to the front, that is so hard in EB due to the movment points (I'm not complaning about the movment points here, I know why they have to as they are). Hopefuly therefore, I'll be able to work out some method of giving building times an upkeep cost, but I don't know yet. Is this more or less what you were thinking Zarax and Basileus Seleukeia? (If you want to I would be more than willing to do some coperative thing between the three of us)
