To start this off, I am aware that the game is still
sold by CD-ROM Access. Before going further, I must point out that this site may very well be selling illegal reproductions of the game--my limited searches have shown that every other game on their site has either very few copies available, or none at all. Why, then, would they have 400 copies of a game so unknown that it has sold
around 54 copies in the last 5 years? Not only that, but 400
jewel case-only copies, when Terra Nova, as far as I know, never had a jewel case release. To top it off, they couldn't have ordered a shipment of 400+ copies, as Looking Glass (sole developer, publisher and license holder) folded in 2000, while the first Wayback listing for Terra Nova's CD-ROM Access page only dates back to January 2001.
It doesn't make much sense unless you assume that they are selling illegal reproductions. Since I didn't find any Abandonia policy about online stores selling
unofficial copies, I decided to post a request, and let you decide for yourselves if the game is abandonware.
Terra Nova was developed and published by Looking Glass Studios, and it is among the first tactical first-person shooters ever. It's difficult to find versions of the game on the Internet, but there are non-ISO downloads under 40 MB. These lack cutscenes and possibly speech, however. In all, it might be possible to get a version of the game under 40 MB, and definitely under 100 MB, depending on what files you left in, and what compression type you used. It's a great game worthy of being on Abandonia, even without cutscenes and speech--also, the story is a bit on the thin side, so its removal would not make that much of a difference. If it's decided that the game is not yet abandonware, I think it at least deserves a page on the site with a review and screenshots, like many "Sold" games have. Your decision, though.
