I actually remember reading Zero, I had the Issue 0, the pre-release taster issue. Loads of the writers in Early PC Zone came from Your Sinclair, another 'legendary', almost genre defining magazine.
I have quite a few of the early PC-Zone, from about issue 18 or so, till about 1999-2000
As for 'i don't get cover discs' You have to remember these magazines are of a time when not everybody had internet... Broadband wasn't even invented... People got their games from friends and sneakernet. Even if you did have internet, it would have been 28.8 or maybe 33.6 modems and latterly 56K and digital distrubution as we know it today just wasn't happening. You were much more likely to send of some floppy disks and get some back from a friend. Hell even CD writers, didn't become remotely affordable till the late 90's Peoples hard disks were 4 GB if they were lucky.
