I've been to quite a few LAN parties all in all, though one of them was a major, a gaming tournemant, which, though still fun, wasn't as personal or fun as the ones I've been to or hosted myself. Some of my more memorable ones has to be my first, where we kept played until we couldn't keep our eyes open, which fun at the time, really messed up my sleep for the next few days. Another would be the summer LANs, gaming all day, going out at night and getting drunk, sleeping late the next day, only to wake up and game some more, rinse and repeat for a few days. Good times, good times.
