I remember visiting those in the early 00's, the last years of so-called «computer clubs» in my country. I've lived in a small town, kinda rural area, so many of my friends still didn't have an PC in their households.
In spite having an PC myself, it was enjoyable to gather together and play Quake 3/4, Doom 3, Unreal Tournament, Counter-Strike and various UT2004 mods.
Good times.
