I have a quick question. I recently bought Civ 4, Warlords and Beyond the Sword all separately. My question is about patches. I am going to install them all on my computer and I was wondering which patches I would need to get. Would I have to get every patch, only Civ 4 patches, only the recent patches, the Civ 4 patches before I install the next game or something else. Any help would be appreciated.
