my friend and i tried to play empire earth with different solutions on the other web sites but game didnt work. i wish gog had a game server so we can play games that have multiplayer support without extra effort.

It would be nice, but it would also almost certainly come with some sort of subscription. Right now Mr. Gog doesn't have a lot of staff, and as such I doubt that there's enough people to run the servers as well as whatever else needs doing.

I'd personally be more likely to get into multiplayer if it was restricted to people who are members here, but it seems a bit much to add to the overhead just to play with other customers.
