It's taken 2 decades to appear, but this fan-made spiritual successor to Command & Conquer: Renegade has finally hit 1.0: '12 years of beta testing has led us to this'

Renegade, mastered.

For some reason I thought this was going to be an open-source community effort, but it’s not. It’s proprietary and made by an indie studio called Totem Arts.

Disappointing.

That’s not the end of the world.

I am huge supporter of FOSS, whenever possible I use FOSS applications on both desktop and mobile. But indie games is actually one area where it would make sense to have proprietary engine and art (albeit maybe for a period of say 10 years for the engine and a somewhat longer period for art).
