There were already many, more famous games they had already released as freeware (no source AFAIK however).
By the way, since we're talking about Apogee/3D Realms, I think we could consider many of their shareware episodes OK for the site. (Yes I know this isn't the Staff forums, let's have some user input.) :P Not changing our current rules, but because:
- They have too big a place in gaming history (Duke Nukem 1, 4 and 3D, Wolfenstein 3D, etcetera).
- They aren't demos or crippleware or anything of the like. They are self-contained episodes, with an ending, boss and all. As a matter of fact according to the current standards of the industry, they would be full games and you would be charged for them. Then of course you would be charged again for the subsequent episodes which would be called "expansions". Actually the additional episodes of most of these games could be purchased separately as well as the whole bundle.
What do you say?
