Er, most the games in the archive are still for sale if you look through most of the online shops (new, not second hand).
Not second hand? Depends on point of view, and how you define it.
I wouldn't want to see ORIGINAL distributors confused with "ordinary" selling firms.
According to my knowledge, APC-TCP games are *made* and *distributed* by the company with same name.
Games sold by forematt & consorts are only distributed, but were produced by 3rd-party companies, with a lot of them being defunct now.
If the original company is defunct, it *MAY* as well be considered a kind of second hand, even though the games sold at forematt (et al.) are supposed to be sealed and in mint condition.
