A couple more questions have been asked:
There's about a 50/50 chance for a territory to have a resource in it, so don't be surprised if some don't get resources.
At the end of your turn and before income for the next turn, you must have £0 or more available. You can't use next turn's income in advance. If you can't afford the thing now, you just gotta save up.
Couple more questions:
1. Relating to expenditure, can players transfer funds between each other on the same turn? In essence, can one player act as a bank for others by lending money (and hoping the other will not default on the loan)?
2. Fortifications provide a set bonus to defence (e.g. Walls provide +5 Defence vs ground units) and have a Siege Resistance level (1 for Walls). Am I correct in understanding that Engineers can be used either side of a siege, both to break down and buff up Siege Resistance?
Ex. 1: Alice has a province with 1 Archer and Walls. Bob attacks with 1 Macemen and an Engineer. Bob's Engineer has a Siege Break value of 1, which is equal to the Walls' Siege Resistance value of 1. Therefore Alice's archer fights without the wall bonus of +5.
Ex. 2: Alice has a province with 1 Archer, 1 Engineer and Walls. Bob attacks with 1 Macemen and an Engineer. Bob's Engineer has a Siege Break value of 1, which is equal to the Walls' Siege Resistance value of 1. However, Alice's Engineer adds Siege Resist 1 by virtue of being in the territory and defending. Therefore Bob's total Siege Break is 1 while Alice's Siege Resist is 2. Alice's Archer therefore gets the +5 defence bonus because the walls are intact (the engineers are mining and counter-mining, presumably).
Ex 3: Alice has a province with 1 Archer, 2 Engineers and Walls. Bob attacks with 1 Macemen and an Engineer. This time Alice has Siege Resist 3 and Bob has Siege Break 1. Although Alice has plenty of Siege Resistance, additional engineers do not increase the defensive value, so the Archer still only gets the +5 defence bonus.
