That's because the Dev makes it up as he goes along (& these days it really shows), as opposed to his original claim that it was written beforehand,... all 30 PDs of it. Most fans now accept that this was probably no more than an outline. I'm guessing it was a very different outline to what exists now. AWAM hasn't so much evolved, IMO, as changed out of all recognition, along with the appearance of the characters. Changes, of course, happen in RL but not in a few weeks or months, such as Dylan's aging 10 years & Sophia's 44DD kiddie's beachballs, sorry, "milk jugs."
Any route that takes more than 2 years to advance should be written out as a matter of course in order to speed things up. That it's no way to tell a story is excruciatingly obvious but also because it effectively ruins whatever the particular tale was, e.g. if Nathalie's maid route ever reappears, it will be in 2035, at the current rate of roll-out. ("Have to be patient" was the Dev's take on this, perhaps not recognising that AWAM fans already require at least the patience of a Saint). That's the issue I was raising with the museum teens. They're "not required on voyage." Things have moved on & there's a need to have Sophia or Patricia call them to say the date is off, as they're both washing their hair, which as I've said elsewhere, in Sophia's case would probably be true.
All the routes & side-shows I was following would go but from my POV, they already have, or might as well have, with the result that there's no more game to play. Maybe I'm in a minority of one. I'll never know. At least AWAM is still catering to incest/Dylan fans, as opposed to being abandoned.
Sam was my teenager of choice & it could be said, his route is still in play. That farce in his bedroom when he put on his artist/expert persona, with the woman of his dreams standing naked before him, instantly wrecked that route for me & I mean full FUBAR. Even the nonsense that is porn logic couldn't explain what's wrong with him, or his sudden acquisition of a professional's skills. It can be explained only by the fact that the Dev considered it was too early for full consummation & that sort of (lack) of action, also serves to spoil the game. If this is now average teen porn, where's the teen sex?
Speaking of incest, (as an amateur historian), I appreciate your references to Ancient Egyptians & the Hapsburgs but the consanguinity between a mother & son gives a roughly 50/50 chance of physical &/or mental impairment. This, of course, would never happen in AWAM, courtesy of "porn logic." Personally, I could see a situation where a new little Dylan decides at age 12, (ref. the look of the youngest shota boy), that he wants to fuck his grandma/mother. That would be bold original irony. Pregnancy, cuckolding & even lactation, (as in Dylan revisits his favourite milk dispensers), have all been placed into the vague, "maybe" category in the Dev's responses to questions. As AWAM is now 80-90% about incest, I'd say all are highly likely if the game lasts another 20-30 years. How many of Dylan's current fanbase will still be interested is another unknowable.
