Ground Zeroes out March 20, 2014, so I bought this box in order to make them all one by one and understand the MGS universe is very complex but simply awesome.
I was very surprised at the HD remaster of MGS 2 "Sons of Liberty" which is really stunning! Games dating perhaps from 2002, but with PS3 and TV 1080p, I can tell you that the game does absolutely not old at all, the revolutionary graphical AMS were already at the time of their outputs, this is so no wonder a HD remastering very successful anyway.
And if you have a 5.1 home theater, games are suitable for even the one of 1999. Very pleasant level audio too!
