I'm gonna jump in and say that I almost cried tears when playing MGS4...tears of pain.
WTF happened to my MGS? I played them all and there is a reason it is called "Tactical Espionage Action"...it was supposed to be about sneaking around and avoiding enemies or at least slit the enemy's throat when they don't notice. Instead I found it better if I was to just run and gun and the game just forces me to run and gun half the time. It might as well have just said "Run and Gun Action"...
I'm in the middle of the third Act and I just lost the will to finish the game. Best Game Eva? I don't know...I ain't gonna protest, but I ain't supporting it either...
