Weighing in on the discussion re: equal playtimes and paths.. Yeah, there's just no way to do it, with a game like this. I try! There's a reason why I try to keep a core plot, with little branches that spring off and then merge back into the main narrative. It helps to keep me from wandering afield and getting lost in the weeds. But, it's just an inevitability if you make certain choices, that you won't have as much content.
Like, if you're on Ashe's date, and you decide to send her home before/after the hot tub, and then watch TV and go to bed instead of doing any of the other possible options.. Yeah, you're going to have less interesting stuff to do that night, and the following morning. Likewise, if I bypass every possible sex interaction, I'm also going to have a shorter playtime. But, those are the consequences of the choices I make.
As far as content paths, I try to balance the light vs dark as much as I can, but the usual thing is that the dark content is a little front-loaded, but may result in less overall, while the light content mostly comes a little later, and will be more prolonged. It's a trade-off.
But, as always I just think.. There's plenty of people who only play one route, despite there being months in between updates. If your playthrough is too short, go back and try some other stuff!
