Metal Gear Solid took Stealth/Action into a whole new level.
This is one of the best stealth/action games on the PS.
The controls at first are hard to get, but once you get used to them, you will really enjoy every moment of the game. Also it can be played as a stealth game, and thus you need to improve your hiding and sneaking skills, or it can be played as an action game where you go and shoot who ever stands in your way.
The boss fights in this game are amazing; some are considered the best fights in the whole universe of Metal Gear Solid!
It's not a long game. It takes like 8-10 hours at first, but there are some special items and weapons you can get after finishing the game. (you need to do some special things in order to get them.)
Overall, great gameplay.
Story = 10/10
One of the best stories ever told! But you must notice; that you need to play the whole series in order to fully understand the story.
(I don't write much on the story side to avoid spoilers.)
Graphics = 9/10
By that time they were soo great. Very detailed environments, very special character designs, and very special effects. Also the cinematic scenes gives a special feeling throughout the game.
Sound & Music = 10/10
For the soundtracks, people still listen to some of the soundtracks, they are catchy and well used in the moment of the game.
For sound effects, I would say epic. Till today, some games lack such effects!
Lasting = 8/10
8-10 hours for the first run, then getting some special items and weapons. Maybe play it again between every once in a while. You will probably play it again, but after you get everything, there isn't much to come back for beside the great experience of playing it!
Overall = 9/10
Such a great game, especially for it's time. Metal Gear Solid brought back Metal Gear in special way and we all know what the future held for such SOLID game!
