There is nothing like playing a game or mod and having fun. Well, than there is a lan. Lans are a load of fun with the right people. Your probably saying how the heck do I set up a lan? Well, fear no more!
The LAN Party Guide is just for you and you can read this and be set up for any lan and tell the person you invited he "sucks" into his face rather than over the pc!
Enjoy :)
