Well, I downloaded Toon's all-in-one mod for Napoleon Total War.
I loaded it up and played a game as Hessen. It started out ok, I focused on economics and building up money and buildings. Then I got attacked by Napoleon himself with a huge stack but repelled it. Then Prussia and Spain declare war on me. Spain isn't an issue. I have no ports and I'm miles away from them. Prussia however is a massive pain in my ass. Every damn turn it sends half-stacks into my territory either just raiding my buildings (which rapes my economy) or sieging my cities. I'm literally fighting every battle myself and fighting it tooth-and-nail.
No one wants peace, and I'm surrounded by enemies. I have barely any cash to spend on anything, and I can't afford to bolster my armies as the upkeep is too much. I can't upgrade buildings to increase output as I have no research buildings and nobody wants money for their tech.
Anyone got any advice for me? It sucks being a mainland European faction with one territory...
