Well any game can be improved.
1. It would be nice for the lighting to have more of an effect on gameplay, similiar to Splinter Cell, just more advanced.
2. The enemy AI in MGS is still kinda pitiful. Guards still walk in patterns you can illustrate on paper. They cluster the same way when they find you. It doesn't feel natural. Overall there hasn't been a large AI improvement since the first game.
3. Enemies disappear after a while as you shoot more and more in an area. More hardware power could have meant the bodies stacking up and not vanishing.
These are just ideas I've conjured up in mere minutes, so I can only imagine the lofty things Kojima has thought up over the 20 plus years he's been making these games. He was probably promised the moon by Sony and felt like the hardware did not deliver like they said it would. Remember being told the PS2 would be able to produce Toy Story-like graphics? I'm still waiting for the PS3 to do it.
