Campaign Systems - World Conquest - The Basics
Overall i think the campaign system would work quite well! Overall I think you may need to add some clarity between different point costs, as i found myself a tad bit stumped when you were referring point/gold costs for men, as I couldn't help but wonder if it was something 'separate' for campaign mechanics as opposed to the actual cost of points for opposing armies in the regular
WHFB games.
Still though, i love the detail that was paid to this in it's entirety and it makes me a bit inspired actually to try and start constructing terrain for use as features, everyone needs more Bretonnian terrain!
