Well then, I guess you can save yourself the trouble of downloading it, as I assume you already do with the user-provided walkthrough. No problem.
Games can always be played without walkthroughs, but they can be helpful to those who are looking for a certain outcome. In this game, finding all three paths (and getting all the content) might be very difficult without a walkthrough. How else do you know whether a choice helps or hurts you with a certain LI. Of course, you can read the 1700 (very) odd pages of this thread to look for guidance. Or you could read the scripts (after decompiling them), but there are a lot of them, spread out over several folders. Not everyone wants to do that. Nor does everyone want to go down a rabbit hole and find out that he/she is missing the content that they desired most.
Oh yeah, using a walkthrough might just prevent people from asking the same questions page after page after page.
I am not trying to argue with you. A lot of people dislike walkthroughs. But a lot of others use them for whatever reason. But I have never seen a game where a player has been
forced to use a walkthrough.
Could DrPinkCake better use his time on something else? Perhaps, but I never listen to music in games.
[I'm listening to Tchaikovsky at the moment.] And I have yet to complain because a developer took the time to put music into his game.
If DrPinkCake wants to provide a walkthrough as a service to those players who might want one, I say good for him.
