Hamachi
 

Hamachi is a program that simulates LAN over the internet. You can use it to share files, play games (:nuts:), etc.

The network name is: Abandonia Network
Password is: pi squared

The only thing left is to find a game that can be played over LAN and we all have it. :wondering:

Abandonia Reloaded is full of Freeware games for Multiplayer.
You could search there, the first I remember is Wolfenstein Enemy Territory ;)

Sweet, I knew having Hamachi would pay off eventually
