Wymrsun 1.6.0 was recently released (announcement on our forums and on Steam). Wyrmsun is inspired by the original Warcraft games and many reviewers on Steam compare it to Warcraft II. The project continues a steady development pace which is always a good sign so I encourage RTS fans to try it out.
Naev 0.6.1 has been released. After a long period without releases until release 0.6.0 appeared in March, this follow up release indicates a return to regular progress for the project. Naev is a 2D space trading and combat game.
I couldn't find a more recent video but here's a bit of a development log of some features for the 0.6.0 release.
Speaking of resurgent projects, Valyria Tear has some news.
The most noticeable change is that I killed a few days ago a very nasty bug that was there from the beginning, making the lua threads never freed from memory. This means the game won't end up anymore swallowing gigs of memory for nothing and crash due to some memory overflow.Well that does sound like a bit of a killjoy, so good to see it fixed. Other changes are in the blog post.
Onto more things slightly more dubiously open source in nature...
ReTux 0.2 has been released. ReTux is a new Super Tux inspired game. It is a completely rewritten (in Python) codebase although uses many of the assets from the original Super Tux so naturally people will mistake the two despite the significant differences. I already covered the IndieGoGo campaign in a previous article.
I would say he should just get it on Steam, sell it there, and be open source outside of that. Perhaps have additional levels in the Steam version but accept that charging for the source code is as pointless as it is ineffective.
