I don't know whether anyone else has tried using Hamachi to play their multiplayer games, but we've found it very helpful. Using the normal means, we haven't played a game more than 15 minutes before it crashes out on us. A soon as we switched to using Hamachi ( http://www.hamachi.com/ I think)
our games have worked perfectly every time.
Has anyone else tried this? Has it worked for you too? I just thought people might want to know about this.
