A better word is "guide" I guess but walkthrough still works I think. It would be a list of events and how to trigger them type of thing rather than a chronological step by step thing. Girl Life for example has a pretty decent wiki for this type of thing and that also doesn't have a "win condition". As well as normal games that are endless or procedurally generated can have walkthroughs they just might be more vague and you may experience things in a different order than the guide lists them.
true but that wiki is severely outdated and contains a very small portion of the possible activities in GL, even within the early game which it covers. I haven't looked recently but I swear the last update to the wiki was in 2018 or something.
GL also has scripted event chains which can be missed if the player doesn't know how to meet the required conditions to unlock dialogue or where to savescum to get the right RNG.
In one of the updates the dev mentioned that the first stage of jobs generally doesn't contain the sidebits that keeps this game on a website like this until ten days of work has occurred. Maybe it would be helpful for that to be mentioned in the "A quick guide to the game" in the intro loading screen or debug menu
Its fun to discover things but I do agree some guidance for possible uses of skills would be nice. Like what is the point of the vocal lessons, how many are necessary before the skill caps out? How many times is it useful to take personal growth courses? The foreign language courses can be used to become a stewardess, but I'm not sure what else it is good for. And you wouldn't know you could use it unless you wandered to the airport via a bus at the railroad district or paid a high price to get a taxi direct. And then view an ad. The airport and Hotel "Flight" aren't even on the list of places in the city
But its not like there's a time limit on discovering that. Rhetorically: why else would you play this game if you weren't trying to explore different paths through life, would you really want a recipe book for it?
