Dozens of movies with director's commentary come out every year, but video games have so little developer commentary in comparison.
Today, Portal with RTX is being upgraded with DLSS 4 with Multi Frame Generation, multiplying framerates, as well as the transformer model for Ray Reconstruction and DLAA, enabling even better image quality. Portal with RTX is also adding RTX Neural Radiance Cache (NRC), a neural shader that improves indirect lighting, as well as a bevy of performance optimizations.
Shaz from GL: "The way Journey evokes emotions through its narrative without using traditional storytelling methods is something no game has been able to replicate."
A gameplay demo of the cancelled Portal prequel F-Stop using recreated assets features no portals, and a unique camera that duplicates items.
I agree completely. There are other things which are needed as well, though. We don't get much Behind the Scenes content, and Subtitles (especially spoken ones). Most games also force you to always start from the beginning and if you're lucky you can later have access to a Chapter Select feature, but that should be open at all times, along with a Rewind/Forward and Scene Selection feature. There's no reason not to have all this stuff.
