I think this remains a poor comparison point.
OG Demon's Souls was an extremely janky, early Ps3 game that was only played by a small number of people. It lacked technical polish, and was difficult to play for the wrong reasons, as well as the right ones.
The Ps5 remake fixes all these problems, brings the game to a much wider audience, as well as massively upgrading the graphics and audio fidelity. It justified its full price tag.
TLOU was already a technical masterpiece, bought and played by millions upon millions of people. Far less work appears to have been done on this version than what Bluepoint did on their restoration and remake. This TLOU remake does not justify the full price tag.
Both are remakes for a modern console. Only one is worth the money.
