I first started with big LAN/Demoscene parties. Between 2003 (when I finished high school) and 2008 (when I finished university) I attended Euskal Encounter (https://ee33.euskalencounter.org/) every summer. LAN parties at friend's places came later, after we all moved out of our parents homes and got our own cars xD

God, how do I miss those days...

I can't believe we lugged our CRTs around too. So much weight being moved around but it was worth it!

I have some great memories of LAN parties at friends playing Unreal Tournament and even that funky Nerf version they made.
