Mount and Musket Battalion is a multi-player total conversion that tries to accurately represent the time period around the end of the Napoleonic Wars (1812-1815). It has historical factions with accurate units and equipment, including different types of infantry, cavalry and even usable artillery.
I took this down not because of it's gameplay, I gave this a 1 because, it was already a too good of a mod, then you sell it out to the public, it is not worth the money to buy a game that came out from a mod.
This reason is from my own opinion, MP mods are too easy to make for even a beginner programmer, I believe that SP mods are much more done with hard work rather than those who make MP mods, think about it, an MP mod takes a year if not months, an SP mod takes years if not half a decade, which will be rewarded with great feedback.
This is my opinion, so don't just bash about it.
