My jaw literally dropped to the floor upon reading the following statement, one which essentially sums up your problem with Metal Gear Solid 4, and shows that you truly do not understand the series whatsoever:
"it needs to study its competition and evolve, delivering shorter cut scenes and superior shooting."
This quote succinctly sums up what your problem with this game, and how out of touch you are with what this game is at its core. You are essentially saying "Metal Gear Solid 4 should change what it is - a unique, extremely story driven, sneaking/stealth game - and focus its attention on being like 95% of all the other shooters out there". I literally am still shaking my head that you would even imply something like this, because you are literally telling Konami to suck the heart and soul of this game, what it is, what it has always been and stood for, and replace it with something that you can get from numerous other games on the market. As I said before, if you want Gears of War, or Halo 3, or Call of Duty 4(games that have nice short cut scenes, and plenty of superior shooting) I would be happy to send you a copy of each game for you to play and enjoy. Unfortunately for you, this is not what Metal Gear stands for, and I pray to the executives at Konami, and Kojima himself, and any deity that will listen, that if a future Metal Gear Solid game does come out, it will not be anything like those games either.
