Almost too many to name. Some big highlights:
-Getting dropped off at the arcade for the day with my friends, $5 in quarters between us.
-Spending hours getting Tunnels of Doom loaded up on a TI-99 tape machine, then playing it all day long with my friends.
-Seeing an NES in action for the first time at a "rich" friend's house. Hanging around with my friends playing Super Mario Bros. until our thumbs bled.
-Renting NES games on the weekends and playing through them with my friends, staying up way too late.
-Playing PC RPGs in a friend's attic apartment in high school (Ultima 7, Elder Scrolls Arena, etc). Spending hours and hours swapping saves and doing hex edits.
-Traveling for an hour to see Mario 64 in action at a mall store demo station.
-Playing Goldeneye 64 endlessly among my 5 housemates in college.
-Playing Baldur's Gate on a PC alongside my then-girlfriend who was playing it on her computer.
-Discovering World of Warcraft, and playing through to lvl 60 with one of my friends.
Looking back at that list, I realize that the common thread was the social element. As good as games can get, the thing that has always made them exceptional is the sense of a shared experience
. Makes a good case for the idea that games have always been "social." Blows up the stereotype that gamers are a bunch of friendless basement dwellers.
