There's a slightly relevant response under "Dragging over your own computers is part of the fun of LAN parties. Why build them in?".

So much fun.... It's so much much fun that LAN parties have gotten bigger and bigger in the past 25 years... Wait, or was it the other way around that this is exactly why people just play over the Internet with each other?

Ah yes, spending an hour getting setup then at least two peoples computers don't boot or the GPU doesn't work...then no one has or installed any of the games you're hosting. Good memories
