I love the Metro series; I played 2033 near its release, beaten Exodus three times (once at release and 2x after release of the Enhanced edition) and just recently beat Last Light Redux. I should probably play 2033 Redux now.
Closely related, I’m very excited for STALKER 2; Shadow of Chernobyl was my first love back in 2008 and I’ve played all three of those a bunch of times.
Proper spatial audio, ie not the DSP effect that upconverts stereo, but something like Atmos or DTS:X that’s sending object based audio to an arbitrary number of speakers, does sound better to me on headphones in the few games that support it. The only game where use it regularly that I can think of is MSFS, but it does sound better than headphone stereo. You do have to pay Dolby to use it, or buy headphones that come with it, however. Sounds best on my 5.1 home theater, but also does a good job with binaural headphone output.
