Apparently, you need to have gone through 300 years worth of college education to get even a grasp on what the story is.
MGS 1 - 5/10 - good graphics for PS1, awful control
MGS 2 - 3/10 - Good graphics, what the **** is going on? Awful control.
MGS 3 - 7/10 - Good graphics, good gameplay, what the **** is going on? Mediocre control
And now we come to MGS4, which is the same.
MGS 4 - 4/10 Great graphics, abysmal story, what the **** is going on? Poor control and gameplay.
Why do people like these games? They are atrociously written, mediocre gameplay, and blisteringly bad control. (You shouldn't need to hold down 3 buttons to shoot a damn gun, Kojima)
Graphics - Great, but getting more and more outdated. 8/10
Story - I couldn't even understand a sentence due to the poisonously bad writing and probably the most confusing plot of all time. ZERO/10
Gameplay - Holding down 3 buttons at the same time hurts my fingers. 3/10
Length - Sure it's lengthy, but why would you want to keep playing? 5/10
Overall Enjoyment - 4/10 = poor.
