Why that one, when a DRM-free Windows version can be purchased from the original author
(the best way of buying a game there is)?
You have to be a clever consumer though, as some of the games mentioned are now freeware, or there is no way to know now who owns the copyright and therefore are considered 'legal abandonware'.
The problem with who has the legal copyright for these old DOS games would make it impossible for G.O.G. to be even able to approach anyone to get permission to sell.
Yes, it would be really difficult and time consuming. GOG.com still looks like the best chance we have these days.
no one would expect steam to carry free games.
In fact, Steam does offer a free game
(not that it's not a demo of another title, though).
Wasn't Descent 1 a DOS game? I'm not completely sure, but that would give us hope GOG can also offer us DOS games ;)
Yes, Descent 1 and 2 are DOS games. They use DOSBox for the emulation here.
That's a disappointment for me. It was a disappointment when I bought some DOS games from Steam, because I thought it would be so cool to have them run in correct screen resolutions and fully support Windows gamepads. I guess nobody has the power to port them nowadays.
