They seem to indicate that, in addition to being a jag fest with laughable textures, it also looked pretty darn drab.
Okay, I see. Because you don't like the way it looks, you're just going to lie about its properties.
By any objective measure, the game is not a "jag fest". It has object-based and camera-based motion blur, bloom lighting, and is scaled to its output resolution. All of these elements cause the image to be smoothed, and compared to other games of its time
MGS 4 can't be classed as among the most aliased.
By any objective measure, the textures are not "laughable". Like other games of the period, some textures are very low-res due to memory constraints. But others are fine. You can see this in the pebbles of the first shot I posted, the weathered wood of the third, the stonework of the fourth, the painted wall of the fifth, and the printed text on the exosuit in the last (this text is readable up close).
MGS 4 is not the best game of the time in this respect, but it's far from the worst or even below average.
"Drab" is the one comment that can reasonably be justified. The game does have a desaturated color palette. But again, this was far from uncommon or notably bad compared to the games that came out around it. It's a knock against the period, perhaps, but not a thing that made this title stand out.
