With CivV coming soon and requiring Windows7, should we be concerned about people upgrading from Windows XP during the course of this SGOTM and causing problems for the cheating checker? My kids have a ton of old programs that may not work with Windows7 so I've been putting off the switch. For that matter, will CivIV still run on Windows7? I fear change.
Hmm, where did you read that CivV requires Windows7?
The official Civ 5 site states
Minimum system requirements
Operating System: Windows® XP SP3/ Windows® Vista SP2/ Windows® 7
Recommended system requirements
Operating System: Windows® Vista SP2/ Windows® 7
I'm running CivIV on Windows7. Anyone upgrading to Windows7 will face the usual hassle of Windows protection features. The HOF site has a page for Windows7 HOF/BUFFY support.
