Hello,
I have bought nearly every DVD that Mort has produced and am happy with every one of them. As he mentioned, each one comes with coverdisks/tapes, bonus magazines related to the main subject, and lots of other extras. To me it's worth the money to avoid having to track down all of it on the net, and it's an invaluable resource for someone like me who's both into old mags and into the computer games marketplace of the 80s and early 90s, before there were really any very good American mags covering it.
If you think the prices of the DVDs are exhorbitant, I invite you to try amassing a complete collection of any 20-year-old magazine, much less one devoted to video games, and come back to me again. I've done it for several obscure computer mags, and it is a major time and reasonably major money investment.
(Mort has also allowed me to use the covers of the magazines he's scanned for my website, if I ever actually get around to European mags. He's an extremely nice guy and any project like Retromags is well blessed with his support.)
