I don't think I have the most suitable setup at home
What setup do you have?
Anybody out there that can point me to something reliable I can read to enlighten myself as to what I might need and things I need to account for?
you want to have a party, playing a game where all clients MUST connect to the internet.
there is no offline way to play a lan party, you must connect to servers where the world is hosted.
what you need
to do this is,
a computer for each player,
a way of connecting them all, (which could be wired, wired via home plugs or wireless)
and a fast enough internet connection for everyone to be online at the same time.
wired connection is best, then wired via home plug, wireless would not be recommended for online gaming... but the biggest bottle neck will be your internet access (unless you have some super fast line...
You may do better finding a game where you can have the whole game, and host the server in your house with the players for the best game play experience.
