Could be relevant, seeing the direction in which the mainstream game engines are going.
I didn't really like any of the already existing options, so I tried to make my own and it turned out to be easier than expected.
It's sort of like a low-budget Unreal/Source, but with open-world streaming support and it is free and open source. Very old-school. But optimized for more modern hardware. Very fast too.
Still not production ready, but it seems like it is mostly working.
I want to finish a few larger projects with it to see what happens.
Btw, the name is probably temporary.
