You could tell people that it's like travelling to Japan and China. The story also is still one of the best. I can't think of another game with a more riveting story. Also S1 is better than 2 cause it emulates life better. I actually had fun driving the forklift. I even got a forklift license IRL because of it. And got into martial arts too. The story also, being about youthful revenge tearing Ryo apart inside, and all his friends he met along the way trying to help him release that anger, is something I can relate to after the fact of playing them 6 times each, it's an aspect of the story I did not pick up on when i was younger. It's something younger generations might not yet understand, about the story. When I just replayed it, I caught things I never noticed before, like how all of Ryo's friends, especially Fangmei and Joy were so concerned about his quest for revenge.
I think S1 is better than 2... Because it's set in Japan... and tbh, S2 had some areas which were quite creepy, like Kowloon... It's like a liminal space... I even had nightmares about it. Oops I guess that's a bad thing to say when you're trying to sell the idea of playing the game to someone.
And also people who did not grow up with "old" games like Shenmue just aren't conditioned to appreciate them. I've played through S1 and 2 about 7 times each and I'm a 33 year old woman

. Honestly with age, I like the game less, well in certain ways, but like i said there are aspects of the story i discovered that I never thought of before. I think what I liked the most when I was younger was that it emulated Japanese and Chinese culture really good and that was my only perspective of those cultures back then...
As for the newer gens trying to play this game... Gawd, it reminds me of, as a The Sims fan, how so many popular youtubers are making The Sims 4 videos... When Sims 4 is such a garbage new gen game to me... I'm a Sims 1-3 elitist... because it's old gen... and the quality was just better. It's like with Shenmue 3 how every one was disappointed... Ok I really did like Bailu village, the graphics, the gathering and fishing system, it was a relaxing break from the previously tense scenario of Kowloon. I've actually grown to appreciate Shenmue 3.
edit: also what's great about Shenmue and Wong kind of mentioned it, is how Ryo goes from 1 major clue to the next, leading him on a journey, from one martial arts master to another. And it's a good lesson about being stubborn and revengeful. Ryo has to slow down and look at life..Life going on in Shenmue..Instead of focusing on his hatred for Lan Di... It really is a great story.
edit: btw also, here is my youtube stream / vids of Shenmue 2. first vid has Fangmei's birthday, its not a stream but the 2nd vid is a stream and it's the end of Kowloon questline . This is my 7th or so playthrough.
its not completion because getting all those capsule toys is so tedious
