The whole problem with Lifepath is that Crush already scrapped it twice because he didn't know what to do with it! He simply couldn't figure out how to use it within his game. Which is why all those skills and stats were barely used.
And nothing he wrote now makes me think he figured that out... until he figures it out how those skills and stats will be used in the game, all the work on it that he does is practically useless.
That is the problem with a whole lot of mechanics he developed so far... he build them, but they were never used for anything. And were never even mentioned after the update they were introduced in.
Yeah as someone who's fucked around with Twine a bit, making these systems barely helps anything get easier and generally you end up wasting a ton of time to make your game a more bloated broken mess. End of the day you still have to write everything yourself; the most twine will do is keep track of variables and maybe a rudimentary inventory system (which FA doesn't even try to have other than occasionally with the clothes) or economy (which FA could also benefit from).
Like the dice roll shit; if you actually want non-linear results you have to write
a bunch of alternative branches for different rolls. This takes a ton of time and gets complicated and means you're writing content that might never get seen - and crush obviously doesn't want to do that most of the time - so the dice system becomes pointless chaff.
If he'd just keep writing the mostly-linear CYOA scenarios in the world he's created I'd be happy enough. He's a good writer in terms of flow and eroticism, and he could just write female agent spy stories (like his little one-off story last year) and not be locked to this one mission ad infinitum. He could add to the clothing system and do other time periods, sci-fi, WHATEVER, just use the framework to write enduring sexy stories.
Then too, and I know I've mentioned it before, he could also easily add some hub and spoke sections to FA, add a money grind or a corruption grind to make the game gamier.
