Hoozah! Sounds like this one collects all the games that I never got to play.
MGS4: Guns of the Patriots was a PlayStation 3 release, making sure that I never got more than the story synopsis–so I’m definitely glad to see it hit PC. MGS: Peace Walker by contrast was a PlayStation Portable release, which is another device that I never had. Ghost Babel being released for the GameBoy Color makes it one of the few gaming portable devices I actually own, but I never came across the game back when GameBoy games were readily available.
Needless to say, short of Metal Gear Solid getting the same treatment that Snake Eater got with Delta, this is some of the best Metal Gear news I’ve had in a while :).
