With some minor changes (that would make for a moderate amount of reworking the story) I think DOL could be a really good game by itself.
1) Sophia and Liam would be married without kids
2) Patricia and Carl would be family friends with two kids, Ellie and Dylan
While the shower scenes would likely need to be cut since they wouldn't fit, I think 90% of the other scenes could be reworked successfully. Ellie and Dylan could both be infatuated with Sophia, and she could be openly flattered that two young people (I'd make it clear that they were 18+) would be interested in her. You could even keep the Aiden storyline if Dylan was more manipulative. Yada yada yada. The point is it would be ironic if DOL could be reworked into a great game considering it was born from AWAM.
Considering the Ellie/Julia and Alyssa events are two of the best scenes in the game so far, and even progress the storyline significantly, I think it's fair to say that L&P
can do great things without needing incest.
Your suggestion is actually similar to Free Pass. MC is a young woman in her early 30s, married an older man with a college-age daughter. The step-daughter's friends (male and female) all have a crush on the MC, and one of the MC's friends too. MC is even rather prudish like Sophia, but in this case, it's because she comes from a conservative country (Myanmar).
Sorry, color me stupid but DOL is ? Please spell for my 2 cells chasing each other. Inquiring cell wants to know. Thank you.
Decisions of Life. The censored version of AWAM that L&P is officially making on Patreon. Ellie is Sophia's friend, Patricia her best friend, and Dylan/Sam/Jules etc are your standard "lodgers", with Sophia being "Landlady"
