Does anything like this exist for the original Age of Empires games?
Battle.Net has "PVPGN" that covers Diablo 2 up through Warcraft 3, and the Westwood Online games (ish) but searching for an AoE equivalent turned up nothing
I've LANed them "online" many moons ago by using software that made a virtual lan that we all installed and managed to find each other ingame. "Hamachi" I think?
I believe the originals just supported offline LAN play. I remember getting my friend to have his modem dial my modem so we could play together, no Internet connection required.
Check out Voobly. That seems to be a pretty big hub for people playing the original games, I think mostly patched versions of the originals with some nice features.
