I play C&C generals with my friend online, all you have to do is to install GameRanger and join, when done you can create you own room or join others room.
There are so many old games that can played, but only the installed game will be able to play.
You have to install the latest update for the game to work, you can find these instructions online.
cncnet.org is easier just install and play instantly
