With regard to Death Rally, Apogee probably has a permanent license to distribute the game, so they can continue to charge money for it if they want to. Sales are probably low enough that Remedy gets almost no revenue -- assuming that they still get a cut of sales -- so they probably saw no reason not to create a Windows version and give it away for free.
Things are less clear with MVP. I assume that MVP has a permanent license to distribute those games, and Dave Snyder (who I believe was the sole proprietor of MVP) probably assumed that he had the right to set the price to $0 since they weren't selling any more. Maybe he did, but the copyright on at least some of those games could belong to the developers, and they may not have been consulted. Assuming that MVP owns the distribution rights, but not the copyright on those games, they may be allowed to give them away, but they can't declare them freeware. That's one of those "
gratis versus libre" distinctions. Basically, the games may have no price (gratis, or "free as in free beer"), but I don't know if MVP has the right to say that the games can be freely distributed (libre, or "free as in free speech"). From a legal perspective, it may boil down to whether the developers granted MVP a non-transferable license to distribute their games, or if they granted MVP all rights to distribution, which would empower MVP to sell, transfer or extend their distribution rights to anyone or everyone else. Since MVP says that you can't redistribute those games "without our written permission", that suggests that they have the right to grant such permission, but I'm not sure if they do. If I'm right that MVP doesn't own the copyright on some or all of those games, that would explain why Redwood Games continues to sell a game that their distributor is giving away for free.
I always intended to get the answers to those questions, until I found out that Dave Snyder died in 2007, shortly after the last time I was in contact with him. I'm assuming, at this point, that it would be easier and better to contact the developers, but I've just never gotten around to it. Perhaps that will finally happen this weekend.
Edit:
Okay, here's a list of who the copyright is listed as for each of the games that they're giving away.
Arcy 2 | None found |
Crusade in Space | Copyright 1994 Glacier Edge Technology |
GameBuilder Pro | Copyright 1991, 1993 Ed Simpson |
Hoosier City | Copyright 1992 Wetware |
Jack Flash | Copyright 1994 Caps Software |
King Arthur's K.O.R.T. | Copyright 1994 Brandon McMullen |
Pickle Wars | Copyright 1993 Karen Crowther |
Rapid Response | Copyright 1992 MVP Software |
Robomaze II | Copyright 1991 MVP Software |
Robomaze III | Copyright 1991 MVP Software |
Thor's Hammer | Copyright 1995 Escape Programming, LLC |
So it looks like we can say that MVP Software owns Rapid Response and Robomaze II and III. Interestingly the developer, Wetware, owns Hoosier City. Apparently Keith Laverty negotiated a different deal with MVP for that game.
I can't find a copyright declaration anywhere in Arcy 2, even in the license file! MVP is clearly the distributor, but I can't tell who owns the game. For what it's worth, it's made by the same company as Jack Flash, which is owned by developer Caps Software.
MVP apparently does not own Crusade in Space, Jack Flash, GameBuilder Pro, Hoosier City, King Arthur's K.O.R.T., Pickle Wars, and Thor's Hammer.
So this confirms that Karen Crowther of Redwood Games owns the rights to Pickle Wars and can sell it if she wishes. Whether or not MVP has the right to give the game away, or allow others to do so, is a different question.
Crusade in Space appears to be owned by Glacier Edge Technology, which was probably solely owned by Eric F. Dybsand, who died in 2004. I certainly hope that MVP doesn't think that the rights to the game died with him. In death, the rights would belong to his estate.
Escape Programming declared Thor's Hammer freeware upon my request on 16 July 2009 and, interestingly, MVP seems to have put the registered version on their website on 3 July 2009. I know that Brian Cox spoke with MVP (presumably to David Snyder's son Chris) before declaring the game freeware, so that might be why they did it.
