Mission Statement

GtkRadiant is a very old project. There have been many versions over the years, and lots of contributors. In the early 2000's it supported many id Tech 3 games, and even some id Tech 4 games. Responsibilities and interests have shifted a lot around this project, but I think most people will recognize me as the person most consistently involved with the editor over the years.

Now that I have left id, I had some time to sit back and look at all the games based on id Tech that I enjoy playing, and at the level design community around them. I figured it would make sense to resume some maintenance efforts for the benefit of those projects.

We are a small group of developers involved in this 'rebirth' of GtkRadiant, and in the spirit of the above I'd like to call out a few rules that we should try to stick to for this project:

• Stability over new development: This project is about providing a reliable reference implementation of GtkRadiant. We want level designers to come to this site and download the latest build with the assurance that they will get a stable and familiar tool to work with. We may unify some of the 1.4 and 1.5 features and tweak some aspects of the functionality, but we are not planning to write major new systems.
• A small subset of well supported games: In order to release builds at the quality level we aim for, we need active users giving feedback, and programmers with knowledge on the specific game. We will only support the games that meet those criterions. We will consider support for new games 'as needed' if we have mappers for those games interested in testing and programmers interested in helping.
• Support more advanced feature development and forks: Some teams out there do some pretty advanced stuff based on idTech3. They have specific, advanced needs that the main release of GtkRadiant isn't going to meet. So we are putting all the code on github where it can easily be forked and modified.
• Provide an archive of some of the older releases of GtkRadiant: We recognize that some designers will still prefer the GtkRadiant 1.4 and 1.5 releases they are used to. We will keep those old builds around on this website if you need them.
