thanks for the answer. I did not mean the download versions of this brilliant page
I mean that, you can buy in a Shop. I mean for example the Game: Tunnel Rats / 1968 Tunnel Rats. You can buy this nowhere as a CD / DVD version, download-only version. For collectors like me, it is interesting to have a CD / DVD version at home, if there is one. If there was such a additive info for every game, you could save yourself the search. But just an idea
