Funnily enough, I'll be joining a 400-people LAN party in about 3 weeks. Very much looking forward to it, even though the games being played are much different (many games are online etc), and the "feeling" is also different (i.e. no binging a single game until everyone falls asleep from exhaustion)

We still do 2 or 3 smaller, private LAN parties per year at a friend's basement. Over a weekend, with like 6-8 people. Those are very close to the "original" LAN party feeling (whatever that may mean), i.e. junk food, chips, pizza, energy drinks, beer, and playing one or two games until early morning hours, sleep, repeat.

Yes, maybe I am overly attached to the past, but I enjoy it :)
