Top 10 C c-language Projects

  1. xash3d-fwgs

    Xash3D FWGS engine

    Project mention: Switch 2 will be backwards compatible with Switch, Nintendo confirms | news.ycombinator.com | 2024-11-06

    I'm certainly not blaming game makers in general because of the situation of Apple dropping 32bit Intel support, but I think Valve is a different story:

    - They've been very diligent in the past about keeping their games up to date.

    - Valve owning Steam means their flagship games are a strong signal about macOS support on Steam

    - If they really wanted, they could; they certainly have the resources to do so should they want to+; which means, they don't want to, which is a signal in the other direction: they stopped caring about macOS

    + HL1 has a FOSS engine that apparently supports it, and more: https://github.com/FWGS/xash3d-fwgs/blob/master/Documentatio...

    Turing Complete, Actually performant, and possibly crazy enough to work
