Shallow Space, a 3D sci-fi RTS from 2015 that was initially very promising but ultimately ended up in development hell appears to be alive again.
Writing on Steam, the developer made a post back in May titled "What happened here?" and briefly went over some of the issues. Things like limited resources, things not implemented properly, a publisher backed out on them and a key reseller got hold of a bunch of keys which apparently dried up their sales too.
The developer went onto mention that since then they've continued learning, becoming a better developer and they've decided they're actually going to give it another go and finish Shallow Space. They've been tinkering behind the scenes for a few months now and have begun talking a little more about their plan.
In a new post titled "What's the plan?" posted in June and it sounds largely positive. They have most of the assets they need already to "recreate Shallow Space as a more fun game using more modern tech". Additionally, they will shortly be making the game free to play on Steam. Originally they used Unity but they've also confirmed they're moving the client over to the free and open source Godot Engine, with the back-end being written in Python.
As for when? Hard to say. They estimate about six months to get it to where they want but because it's going to be free, they're "not going to get stressed about delivering it again, better to enjoy the journey and the positive community spirit the project has always seemed to attract." and then attempt to bring it to a state where it's fun and eventually look at some kind of funding to properly finish.
