Hello. I have been playing Civ 3 mods and Civ 4 mods, and I have always had this burning question. The question is, how do modders know what version number to call their mods? For example sometime modders post versions that increase only .01, while sometimes it increases .8 or .9. I understand that the higher the version increase the more stuff was done, but how do you know exactly what number to call it?
