Well Pressimage was a PD library at first.
I guess they just asked some authors for exclusive productions, and sold those at a higher price this way.
I remember going in their "physical shop" on Paris, which was a small place with shelves of grey disks.
Asking for some software (probably some tracker, or MODs files). And when i was back home, finding out the man gave me a disk of erotic pictures.
Intentional or not? Couldn't say. But i was really angry about having to get back there to get the proper disk, that i know.
 Aya, the Atari Legend list seems to be "enriched" atm by some pretty wicked titles
