As for MGS1:
“arrives virtually unchanged, as this is an emulated version of the 1998 game, lacking widescreen display or up-ressing, which may come as a disappointment for players hoping to play MGS1 on their 4K TVs”.
Yeah, I don’t think any of them were widescreen until 4.
I’m all for remasters if companies want to make money between longer dev cycles, but I feel like not adding simple QoL things like widescreen and up-ressing takes this out of remaster territory and squarely into just a port.
