I'm looking to run a version of Windows on my early 2015 macbook air with the 128gb ssd. The only thing I want to do is use it to play Civ V just so I can run a certain mod for multiplayer. I was just wanting advice on the minimum amount of space I could partition off and get away with it, which version of Windows would be the best, and how much drivers and stuff are going to take up as well. I know I don't have a lot of space, but I really would use it for nothing other than Civ at the moment. I currently have just under 70gb free after cleaning off some stuff. Thanks for reading.
