Since my new computer is working again (and is quite a lot better now), I figured I’d start playing Civilization IV again. I also decided to give CivFanatics a quick browse to see if there were any cool mods.
The one that caught my eye is called Regiments. It changes the graphics (and the graphics only) to include more people (so you’re infantry for example consists of 11 people) as well as rescaling them appropriately. Since it only changes graphics you don’t risk starting an unbalanced game and you should even be able to load an existing game without a problem.
So if you have Civ IV, go get it now :P
