Amazing game, one of the best I've played on the PS3. It would probably be in my top 10 must-play games.

Of course, it's also available on the PS4, where the experience is likely to be even better (I say likely because I haven't seen it on the PS4).

In summary:

-The best gameplay I've encountered in a game.
-Very good graphics.
-Great variety in how you can play each mission, with weapons, vehicles, etc.
-Great story, with twists, plot twists, explanations of the past, and the future of the story. I have to admit, though, that it wasn't the best story for MGS. But it's still nice with very beautiful messages.

-On the negative side, in the last part, it has a pretty big lull with repetitive missions. That's the only thing that bothered me.

Also, many hours. It took me 170 hours to complete, and I continued and reached a total of 300 hours.
