I'll start by quoting myself from the last similar thread we had:
It's a difficult question to answer, because it depends on your definition of various things.
It's not possible to see "all" scenes in one playthrough, depending on your definition of "all" - for example, the scene where you meet Naoyuki and Ichiro at your house has different dialog depending on whether you went to Yokosuka Bar first or not [...] And that's making no mention of time/weather variations...
It is, however, possible to see every scene in one playthrough if you're not interested in such variations. As far as I know there's no complete list of scenes at the moment, but there are no cutscenes which lock out other cutscenes, aside from the variations.
Similarly, it's not possible to get "all" items in one playthrough for the same reason - for example, there are six different Nozomi photos you can get, and you can only ever get one per playthrough. But you can get one of every item if you're not interested in those variations.
[...] it's not possible to hear all dialogue in one playthrough - some dialogue locks out others (for example, when you're looking for Charlie and you talk to someone who tells you about Nagai Industries, you can no longer find out about Nagai Industries from any of the others, instead following different dialogue asking for directions instead).
Let's tackle the "100%" question. Are you interested in all cutscenes? All items? All dialogue? All notebook pages filled? The maximum number of each or any of those things attainable in one playthrough?
So, for a while now I've been considering doing a Shenmue 100% "Speedrun". I put speedrun in air quotes because its hardly a serious category. More of a fun run. Before I start though, I want to get a gauge of what people consider 100%. Naturally, I'm including all capsule toys (even the ones on passport) and medals but my bigger question is about some of the more obscure and easily missed collectables. Should photos and memos be included? Or what about the locations and character profiles in Passport?
There is nothing about this that would constitute a "fun run", because you have two things in combination:
1. Capsule toys, which are RNG hell.
2. Dreamcast, which lacks save anywhere and is slow to save and reload.
Secondly, if anyone wants they can contribute routs or meta-data, like percentage rates for capsule toys, to help build the run. I do plan on doing the routing myself but I imagine several people already have a mental rout they've put together and would like to contribute. Since you can just grind for money, I want to try to restrict the run to:
- As few days as possible
- No work day 2 abuse
I realize that things like Dural Gold can kill a run like this but I like the Pass/Fail aspect of the run. It will keep me more interested than a lengthy grind will and make me more likely to attempt the run multiple times. If the run is in-fact impossible, I'll loosen up the restrictions. Mind you, that's impossible, not very-very-hard.
You realise that the Pass/Fail aspect of the run will lead to a lengthy grind, right?
If you're going to be doing this on DC, save scumming is basically out of the question. With that in mind, the fastest way of getting raffle draws is by buying the chocolates etc.
Winning all prizes in Dobuita Tomato Mart would take an average of about ¥12000 (further experimentation needs to be done on this); same for Harbor Lounge.
I currently have no idea how much you'd expect to spend in Abe Store because I've yet to win a single Dural Gold after more than 3000 attempts. To put that into perspective, it would be cheaper to buy the ticket to Hong Kong in Global Travel Agency than it would to get a Dural Gold. The only way you can earn enough money to do this is by grinding the forklift job... by which point you get only a couple of minutes total to spend in Abe Store.
Looking at the money situation:
Start: ¥9800
Daily income: ¥16000 (¥500 per day; in order to get all cassettes, your last work day has to be at least January 3rd; if your goal includes "as few days as possible", it means your last work day IS January 3rd, which gives you 32 days of income)
Ryo's bank: ¥36512
Fuku's piggy: ¥39634
Forklift earnings: ¥(2000+300*20+350*16+400*20+450*16+500*18)=¥37800 (as your goal includes not repeating work days; I assume "no work day 2 abuse" also includes not repeating the other days either)
Your total income across the run will be ¥139746.
Cassettes: ¥6600 (¥300 each, and 22 of them are available to buy)
Shenmue treats: ¥360 (Chocolate, Potato Chips, and Caramel are ¥120 each)
Cat food: ¥(90+90+180+500)=¥860 (you do not need to buy Dried Fish or Milk)
Light bulb: ¥90 (every other item in the shop can be found instead of being bought)
Arcade prizes: ¥500 (assuming you can do well enough first time in every game...)
Move scrolls: ¥(500+1000+1000+1000+2000+3000)=¥8500
Trips to the harbour: ¥6400 (¥160 each way, 20 trips in total are necessary - ten required in the course of the story, eight more for Lapis clues, and two to get a map of the Old Warehouse District)
Lapis clues: ¥11700 (¥300 each, 39 in total)
Ticket to Hong Kong: ¥69000
Cost so far: ¥104010. This leaves ¥35736 to spend on things that require a great deal of luck.
Assuming you have the best luck in the world:
Capsule toys from machines: ¥13500 (¥100 each, 135 in total)
Winning Can: ¥100
Slot House: ¥100 (minimum spend; you'll have to win 23 prizes on this)
Abe Store prizes: ¥600 (¥120 each, 8 in total - but 3 are free thanks to already counting Shenmue treats)
Tomato Mart prizes (both stores): ¥0 (¥120 each, 15 in total - but all are free thanks to cassettes)
Minimum cost of luck-based items: ¥14300, leaving ¥21436 spare at the end of the game.
HOWEVER
Abe Store prizes (realistically) must be unlocked before starting work; you can put off a lot of things until then, but 14 trips to the harbour, 32 Lapis clues and the ticket to Hong Kong must be spent first.
Total income pre-work: ¥98946
Total necessary costs pre-work: ¥83080
This leaves ¥15866 as the maximum amount to spend at Abe Store, and a lot less time to do everything else.
You have the opportunity to fail an RNG roll about 175 times. Bearing in mind that this includes Dural Gold (for me, 3360 attempts and counting...), FOUR console figurines (also considerably rare), and 21 jackpot wins on the slots (9 on a 1-coin machine, 7 on a 5-coin, 3 on a 10-coin, and 2 on a 20-coin, an expected investment of about 23k tokens = ¥115,000) then you're going to be spending the rest of your life attempting this run.
Making theses assets is part of the reason why I'm looking for what should be included in a 100% category as early as I am. I'm also considering programming a graphic in SDL to show percent completion but that idea might get canned.
I have a tool myself showing % completion (very rudimentary, text-only, and unreleased because I never meant it to be). It uses the following:
Notebook pages (/400)
Learned moves (/20)
Story items (/69)
Gacha (/275)
Cassettes (/28)
Maps (/25)
Pawnshops (/12)
Scrolls (/25)
Shots viewer (/48)
Event photos (/12)
Passport unlocks (/72)
Shenmue Collection unlocks (/26)
Achievements (/55)
Lucky Hit boards played (/107)
Fangmei's confession (/1)
Obviously this is for both games and takes re-release things into account; with that in mind, even with my very slow and methodical playing through, this doesn't go above 96% - and that's even with the main focus of Gacha being in Shenmue II, where you can actually obtain a Dural Gold. The capsule toys are the primary reason for this.

EDIT:
If you wanted to make this more "fun", then go for a true 100% - require EVERY notebook entry, and EVERY item variant - this needs a minimum of six playthroughs to do. While that sounds worse to begin with, it gives you a LOT more leeway when it comes to the capsule toys, as you get about ¥220000 more in total to get them with, meaning you can fail an RNG roll about 2000 times.
