Because we know truely that this is one of the greatest games ever made. Not graphically, not from a sound point of view, not from anything specific....
It is a truely special game that, since its release, not one game has been able to recapture the collective qualities which make it great. When you truely love something in life, you love it for all its aspects. Its good points. Its bad points, And Shenmue has a lot of both. But one couldnt exist without the other, and thats what all comes together. It makes it a masterpiece, which slowly but surely, people have came to understand.
It was made in an era where games were games . Pre open world GTA. Pre kill anything that moves Modern Warfare. It was a 101 lesson in how to generate an emotional connection with a piece of coding, some art and sound, a little console and a controller.
It was the right game, for the right people at the right time, and after 14 years, people are finally waking up. Older gamers who get drunk on its nostaliga, and new gamers who have seen through the facade of a killstreak or AAA game which has just been rehashing the same krud for 5-7 years. Its a gamers game, and people are realising that.
