What I miss is when I lived with 6 other students in a big, and very bad condition, flat.
Within about a day we'd all linked up all the PCs on a LAN network. We were all gamers.
Now yes we did all the drinking, girlying, partying, the works .. but on those idle Tuesday afternoons when no-one could be bothered to go to lectures we ALL used to network up.
I remember 3 favourites
1) Red Alert
2) Xwing vs Tie Fighter
3) Age of Empires 2
now these games used to go on for HOURS -- and we often divided up into team battles etc. We even used to agree to pause age of empires 2 once an hour for 5 minutes so we could have secret 'strategy meetings' with our team.
It was much better than normal PC gaming because we were all physically in the same building -- you could hear people IRL swearing as your tanks smashed through their walls -- or going to the loo as fast as they could (at which point you send the attack in also as fast as you can!!). Oh, and we all drank beers throughout, and afterwards discussed 'cool' bits of the battle ..
It was really good -- kind of like a LAN party whenever you want, with no setup, with a load of really good mates.
Gaming at it's best ...
