Hi all. My friend and I have completely different PC setups but a shared passion for Civ 3. I am on Windows XP (and have Civ III Gold) and he is on Windows 10 (with Civ III Complete) which is causing big headaches for playing online together. So far my investigations have identified: - Steam can't be used (as Steam Civ 3 Complete only permits play with other Steam players and Windows XP can no longer access Steam). - GOG Galaxy can't be used (again, because Windows XP isn't compatible with GOG Galaxy, so I can only download an offline only version of Civ III Complete from GOG). So what I am proposing is getting second hand CD copies of Civ III Gold and get both versions of 'Play the World' updated to the same patch, but I'm not certain that: i) those CDs will work on Windows 10? ii) whether direct connect will work between the same game on such different operating systems (assuming I can get around any firewall/ports issues) Can anyone advise on above two questions, or do I just need to take the plunge into the unknown!?
