The DreamHack festivals, held throughout the year in Sweden, are the world's biggest LAN parties. How big is big? The one starting today, DreamHack Winter 2011, is the biggest of the lot, and should pull in over 12,000 people.
The event set a world record for LAN parties last year when it drew 12,754 computers and 13,608 humans, so this year's should be just as big, if not bigger.
If you ever wondered just how much crap has to be put together to sustain that number of people all playing PC games in the one place, well, now you know.
