Commercial Software Licenses
Commercial Software Licenses
The Quake specific licenses are discussed in more detail on a separate page. There are quite a few others:
Notwithstanding the foregoing, you may create a map editor, modify maps and make your own maps (collectively referenced as the "Permitted Derivative Works") for the Software. You may not sell or distribute any Permitted Derivative Works but you may exchange the Permitted Derivative Works at no charge amongst other end-users.In later releases like DOOM 1.666, the license changed to take account of possible commercial uses like pay-per-play, and the use of idbsp that had been released earlier without licensing. This later versions refer to the Data Utility License that is supposed to apply to all, even non-profit, tools and utilities - again a rather doubtfull attempt to get a hold of the voluntary support by the community.
Then there is the license that covers possible use of the generously released Wolfenstein 3D source.
With the Quake qtest1 release, we got our first Quake related license agreement. It will be interesting to see how the actual shareware license will be geared with respect to levels made from scratch, and third party profit and non-profit tools, as well as I am quite curious about the definition of Permitted Derivative works. The complete overview of Quake specific license regulations and clarifying statements is maintained separately.
The Heretic" license by Raven Software is nearly identical to those used by id. The Duke Nukem 3D shareware license file by Apogee/3D Realms is quite different:
By distributing or permitting the distribution of any New Level, all owners of any trademark, copyright or other right, title or interest therein (to the extent different from the Game as originally distributed by 3D Realms) grant back to 3D Realms an irrevocable royalty free right to distribute the level.This kind of license is probably a blatant violation of copyright laws, and inacceptable anyway for obvious reasons.
