Forgive me this off-topic, but i feel i must warn fellow Civ fans here. Don't use Windows 10. I have insider information that Microsoft plans to change Windows 10 into pay-per-month one year since its formal non-beta release. I have no idea how much per month it'll be, but knowing Microsoft pricing policies, i doubt it'd be insignificant amount... And, of course, it spies on you, too. Of course, Windows 7, Windows 8.1 and server versions are spying too, unless you prevented (or removed) corresponding updates as described in http://www.infoworld.com/article/29...w-all-collecting-user-data-for-microsoft.html - but in Windows 10, there is LOTS more of such problems, and much of communication between any Windows 10 machine and Microsoft server - two-way communication, - can't be disabled despite what user may think on the subject, as reported by http://thehackernews.com/2016/02/microsoft-windows10-privacy.html . Stay safe!
