If I remember correctly, I played mgs 1 with keyboard on Pc. You had to spam "space" for cqc.
And it looks like you could
technically use a mouse for MGS1, but it was for like goofy slidestyle movement, where you assign mouse movements to the cardinal directions. (Mouse also worked in menus.)

MGS2 would be pretty much the same thing. (Maybe you could mod it for aiming, but then you would need to move Snake with a mouse, which is dumb but also counterintuitive to switch controls and aiming all the time.) The original PC version of MGS2 didn't even have the cursory menu mouse features that MGS1 did.

MGS3 I guess would work with a mouse (Subsistence cam,) but even that wouldn't work the way people expect a mouse to work because of the intentional camera limits. (There never was a PC version of MGS3, was there? )
...So, seems weird that some people are acting like this breaks the game because not everybody has a controller for their PC.
Konami went controller-only in 1999/2002, back when it wasn't as easy as plugging in any controller for any console in the house into USB or BT.
In general, sure, no reason to not allow remapping the controls to keyboard. (I'm guessing that's already a thing, although 2 and 3 are expecting analog input to work so that's a problem unless yet also add in like shift-modifier?) Mouse, though, that's a redesign of the game and a clumsy feature at best.
This feels like something people are angry about on principle but aren't really thinking about what they're angry about. I get it, "choice", but it's a choice nobody will ever use because the end result must likely wouldn't work.
The same way the old MGS 1 and 2 PC ports work.
See above. Unless these docs are incorrect, there wasn't really m/k support in the old PC 1&2. There was k, but the m was practically unused or worse, was the worst way ever to play.
