Yeah and the PS5 remake looks like a bigger jump than the PS4 remaster. It deserves this attention because it's the best example of the AAA game so far. It took the mantle from classics like Half Life 2 and Bioshock. And they're making an HBO TV show based on it. So yeah it earned PS4 and PS5 versions.
I got the PC versions of Skyrim and GTA so no rebuys there. But again, these are mega-hits. People continue to play them, spanning hardware generations.
