Just started a small new project: a bare bones IWAD (main resource file) for making standalone games with GZDoom. This makes it so you can build something with GZDoom - probably the most advanced, feature-rich, quickly evolving Doom port - without needing to own any of the Doom games, or be beholden to Doom's genre or design.
More info in the TODO list:
The compiled resource file is only 87kb, but includes menus, a single minimal level, and some placeholder assets. You can download this, open it in SLADE and start adding your own graphics, sounds, ZScript files, and of course levels.
The next step will be to copiously document everything and add a PK3 (new-style WAD, basically) of example content, so that people who aren't yet familiar with GZDoom modding can learn the engine and build games with it.
5 years ago I talked about a project called DECK - the Doom Engine Creator's Kit. This is not that.
DECK would be a full Klik & Play style library of libre content, to give creators a firm starting point for making levels even if they don't have spriting or texturing experience. I'd still like to do that someday, but I'd want to crowdfund one or two professional artists to make that content. So it's a "someday" project. I don't have the time or energy for it right now.
Server run by the main developers of the project It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
