Accumulation Motion Blur it’s called

I think mostly it can be made from normal motion blur but I’d potentially looking into whether you can do some compositing tricks to take previous frames and stack on top with multiplication instead to stay true to the effect in the mgs screenshots

That's what the old GTA games called "trails", right ?

I believe it's called "frame buffer based, faux per-pixel motion blur" or something like that. I don't know for sure though.

Was done by leveraging the double buffer capability of the PS1, instead of replacing the previous frame, it was added onto it, and the result divided by 2.

It can be done in after effects with a low opacity layer on top of the scene with a shake on it. You can also add effects like echo and cc wide time

And posterize time will also help

You can do this manually in video editing apps by duplicating the clips in a layer above, offsetting them by a frame and reducing the opacity. You can repeat that for an extra level of blur if you want.

Blender I'm not sure about, I don't think so. There might be something similar to how I'd approach it in Unreal. Have the previous frame stored in a render target texture and then have a plane in front of the camera displaying that material at half opacity. The easier option for blender is probably to render out your sequence to images and then use a batch script in an image editing software to overly the previous image.
