Dynamic Campaign Generator (DCG) is a mod for the games "Men of War" and "Men of War: Assault Squad" that randomly generates skirmish missions and lets you keep your surviving forces from one battle to another. Some people find this mod tricky to install the first time - please read the readme.txt carefully and ask for help (if you need it) on our forums here on this site, or at the game developer's site.
This is definitely the most useful mod I have discovered for Men of War. The ability to randomize a campaign and create a group of grizzled vets through many missions is very appealing. In fact according to Steam I've clocked over 800 hours on the game. This mod has kept the game fresh the whole time and in conjunction with the ability to alter model files I can basically apply this system with any war fighting scenarios that are available. (Check out the Total Krieg mod for new models.)
I'd give this mod a 10 but the one thing I feel falls short is the lack of a new graphical experience. Despite the reskins there are still some basic issues with model meshing but if you don't care or take it up yourself it's no problem.
In short, this mod is fantastic nuff said.
