I have now bought this game only and I have to say I am thrilled. Allerrdings I think this may be it someone not even make half as much fun, does not know the parts 1 and 2 (for the PS2) and has also played for MGS 4 takes over again with regard to these two predecessors and brings the story (though perhaps somewhat constructed) finally (or unfortunately?) to an end.
I have certainly felt well entertained and the videos are made class, whose length can be discussed.
So in short: MGS fans need it necessarily, all other should play sample or previously get the other parts.
