Hmm... why would those games be released as open source? That's bad business, especially considering that;
Blood --- I've heard rumours that it will be released for cell phones and the likes (in other words it has commercial value still).
Carmageddon ---
Sold
Die by the Sword --- a 1998 game, which is really popular with gamers. In other words a game that would sell really well if it was released as a budget release along with its add-on "Limb from Limb". Meaning that releasing it for free is bad business.
Alone in the Dark --- This game was still sold until a couple of weeks ago, when the last copy was bought. However, as the game is still very popular, chances are high that the game will be restocked in the future.
Dark Seed --- Developed by Cyberdreams, Inc. A company that now is dead, as such the copyright of this game is lost somewhere in the space continuum. It can not be released as open source. Especially not, considering that the artwork of the game is copyrighted H.R. Giger. And what would Dark Seed be without its graphic?
Bioforge --- Actually, on this specific game I believe the commercial value is pretty low. If any of the games would be released as open-source, I believe this one would be first in line. Though, I still don't think it is likely.
Ecstatica ---
Sold
Road Rash --- Electronic Arts releasing something for free? :blink: Well... Abuse is open-source, but I doubt EA will be releasing more stuff for free in the near future.
Rocket Jockey --- Never even heard about this game before, but SEGA is notorious for keeping stuff to themselves.
Mass Destruction --- This game is marked as Unknown in the AW List, so I really don't have any clue what to say about it. :P
