Article: Unforeseen Greatness - The Talos Principle
Wow, check out this update from Croteam.
VR support, Linux support, Vulkan support, better OpenAL, better modding support, and much more for all of their relevant games. This includes The Talos Principle (although it includes most of these things already), Serious Sam 3: BFE, and Serious Sam HD. Basically they want to make Serious Sam have as many options as this game (as if they didn't have enough), and be as close to perfection as possible.
The closest thing I can think of was KOTOR 2, but even that update wasn't as good. KOTOR 2 got a major engine renovation for better support for modern systems, although not as extreme as the full fledged remakes that are Serious Sam HD (first and second encounters). KOTOR 2 got Workshop support, but that's about it. It still breaks above 85 Hz, and they actually significantly DOWNGRADED the sound system by ditching DirectSound3D and not using OpenAL, so goodbye EAX and 3D sound.
