Enough reason to have a PS3!
The story is awesome and very complex, it may take time to sink in properly but it still stands out among this generation and previous generations. But don't be afraid to give Metal Gear Solid 4 a go just because you haven't played the previous games in the series, i for one haven't played any MGS game till MGS4 and let me tell you since i've finished it. I am very into the world of Metal Gear Solid. I was still able to understand a lot of the story and was only confused at a few points.
I could go on forever but i do not have the time or effort.
But let me tell you this, if you have a Playstation 3 or even if you don't just go and get one and a copy of Metal Gear Solid 4 and you will not regret it.
This game is a true MASTERPIECE and i enjoyed every second of it.
Thank you Hideo Kojima.
