Thank You For Playing: Iconic Video Game Magazines is a documentary that just hit Steam. It looks fascinating, since it’s not just about old game magazines, but old Polish mags in particular, tracking their explosive rise in the wake of the Iron Curtain coming down.
In addition to covering the mags themselves, it’s also cool in that it gives you a look at what some of the guys behind The Witcher and The Vanishing of Ethan Carter did before they got into development.
The doco’s in Polish, obviously, but it has English subtitles.
