The definitive version of MGS. New difficulties, settings, etc. Its story is the best in the series, the gameplay is "Solid", and is always a blast to replay. If you want an easy way to play this, get the Master Collection version or emulate it. I guarantee it is worth your time.

Absolutely groundbreaking from top to bottom, on a narrative aspect, cinematic, and technical. Fathered the stealth genre. Revolutionary to the gaming world and make more recognize that, yes, video games are indeed a form of art and start being seen as such.
