Games by last release
- C-Dogs SDL (*) - Top-down action/shooter game that is a Free SDL port, continuation and expansion of the DOS game C-Dogs by Ronny Wester. (Code: GPL v2, media varying CC0, CC BY and CC BY-SA with CC0 preferred)
- MegaMek (*) - The project is active as of 2018 with the latest release being 0.44.0. Code is GPL, but clarification is needed regarding the data files and it may also be prudent to check for trademark issues. Some user-created add-on data files on the website are unfree.
- Indie developed games:
Endless Skyarticle created on 2015-11-14
- Nocturne in Yellow - Engine is apparently GPL (https://github.com/marrub--/GLOOME Readme clearly states that), media license seems unclear, I found this (http://forum.zdoom.org/viewtopic.php?f=19&t=49299&start=90#p868865) post which seems to vaguely imply WTFPL. Seems like additional research is needed to confirm it, game seems rather professionally made so probably worth looking into?
