The older games and even going as recently as the PS4 and XB1 generation, will still be around for the foreseeable future in both official and unofficial capacities, though, with some of those previous-generation titles even having an official DRM-free release on GOG to boot.
And really, there's nothing interesting in the current generation outside of indie stuff, as far as the big AAA releases go, they largely appear to be slop this generation.
