I think the series would have actually been better without the addition of Peace Walker. Portable Ops had already answered the question as to how Big Boss was able to finance the making of Outer Heaven, and that was a good premise to start off with the next Solid Snake chapter (aka. a remake of one of the original Metal Gear games).
Plus, if the storyline for MGS 1 and MGS 2 were to hold true, the AIs in Peace Walker were just way too advance for their time. Even the Peace Walker mech was capable of wiping the floor with REX and RAY, given all of its offensive capabilities.
Damn straight. The plot holes in PW are out of control technology wise. In MGS, you want to push the envelope by making the tech a little more advanced then what it is in reality for that time. But how is it ZEKE has more capability than REX or RAY?
MPO gets a bad rap, not as bad as people think. In terms of story I honestly think it fits better with the over story than Peace Walker. PW didn't really add anything to the story or mythos of Big Boss at all.
Big Boss is so watered down at this point, and their doing MGS5 with him as the lead.
Bring back Solid Snake, enough of Big Boss *********.
