Yeah... thats basicall what I said, so you are agreeing with meIt's definitely not the kind of chart you need to play through the game, but its still kind of useful. AFAIK I've played through everything but I "only" have 122 quests completed. A few have been missed. This chart allowed me to notice theres one more quest I could unlock by having more incest with the little sister, for example.
It would be a little crazy to try to follow it religiously to hit 130/130, but it can help you notice where you can unlock a little more content.
... Why does it sound like you're arguing?I don't get it!, sure it's good for figuring out how to streamline your playthrough if you want a specific piece of content (which doesn't really help Noob players). ...
It's good as a reference, poor as a walkthrough.
