During the Kojima Productions podcast #159, the staff members gave some more insight into the decision to not update the controls of MGS2 and MGS3 for the HD Collection, to something more akin to MGS4 or Peace Walker.

If you're replaying MGS1 in any of its available forms, you'll want to know how to unlock all the best items in the game!

The Metal Gear Solid HD Collection launched in 2011, and is still the best way to play Metal Gear Solid 3: Snake Eater ahead of the remake.
Can’t wait to one day break that game out of the collection vault
Currently playing Snake Eater HD on CRT 16:9, via Scart RGB. Game looks great but not as clean as MGS2, but thats due to the setting. Can't wait for the remake + the next HD collection on PS5.

Months after they were removed from sale, a number of Metal Gear Solid games have yet to return to the PlayStation and Xbox stores.
Konami's too busy with their Pachinko machines to worry over silly little things like this.
I agree with the KP staff here.
You cant just shove modern controls into a game that didnt use or need them.
Leave the camera how it was. How hard would it have been to map aim/shooting to L1 and R1?
True, adding in other features and controlls would ruin the experience. It would be like making a mario game where you can see from anywhere but its basically 2d.
MGS2 was a game of perfection to being with, why bother.
