Finished up Metal Gear Solid 4 the other night and I have...kind of mixed feelings about it. On one hand, the last couple acts were fantastic (besides some of the over-the-top cheesiness) and I was mostly happy with the way the story wrapped up. On the other hand, the first half or so of the game was ehhhhh both gameplay and story-wise. Overall I think MGS3 was my favorite of the saga, but I did really enjoy 4 as well. Still not sure I'll get through Peace Walker and Ground Zeroes before September 1 though, so I may put off playing The Phantom Pain at release.
