Yeah I have to agree, its the biggest gaming disappointment... well ever for me.
Sure the gameplay is solid (lol solid) but the game is so damn repetitive and there is like zero story progression happening for long periods. Whats worse though is the time Ive put into it is more than enough to have finished any other Metal Gear. This one is needlessly stretched out with missions that should have been optional but for some reason are forced on you as story missions. Also I felt the open world while cool, was just completely pointless. Ive played for like 30 hours and the 1 time I enjoyed the open world was when I accidentally ran into the Quiet boss fight...which by the way is still the highlight of the game for me.
