The game is 20 years old. I think the spoiler warning period has lapsed.
That said, I don't think I'll ever find time to play the original Shenmue. But hearing more details about why it has cultivated such a fond following makes me very interested in playing its Kickstarted sequel.
I'm not saying don't read it, I'm saying if you want to play the game, consider playing it without preconceptions.
I think it's safe to say that the vast majority of people who play games now have never experienced Shenmue even though it was a blockbuster title on the 9 million Dreamcasts that shipped worldwide.
And you're not only spoiling the 20 year old version, you're also spoiling the HD remaster that can be bought right now on PC.
