AL is not a bad game. The full story with all the twists and revelations actually would make a good script for a Hollywood movie.
The problem with AL is that it started as a lighthearted Dating Sim where mc has opportunities to have sex with different girls. After some episodes the topics became darker (death, drugs, violence) and there where more consequences, blocking further progress with the main LIs if mc was dating other girls. And then everything turned into a psycho thriller type nightmare. So from start to end AL completely changed target audience. AL is a good choice if you look for a psycho thriller game with some sex scenes, but it is the completely wrong choice for people who look for a lighthearted sex and romance VN. Having to choose between M and M is no fun, accompanying your best friend on his bucket list tour neither.
Since the story of AL in 2020 is widely known, adding some of the dark twists to BaDIK would hardly work since players will recognize the pattern and there won't be any surprise but mostly rejection.
AL contains the blueprint for mc+Maya+Josy threesome, but I really hope that BaDIK doesn't follow AL after choosing "more than friends". (Maybe I missed a scene but) the mc+M+M relationship in AL was strange and disappointing. A man and two women end together in a relationship, they live in the same house, sleep in the same bed, but they don't have sex together. Instead they agree to start seperate dating series where the mc dates one of them or the other. One of the scenes in AL where mc dates Megan with dinner and sex in a hotel room is very similar to the scene in BaDIK where mc dates Josy at home (first college weekend, dinner and sex in her parent's bedroom), except for the ending of the scene. However BaDIK's start with Maya and Josy being a lesbian couple is a much better start than M+M just being BFFs without sexual interest in each other.
