I love Freeloading Family, but the game now makes no sense with or without patch... I respect that FCreations doesnt want to or CANT mention if incest is canon or not due to Patreon, as some of the devs that dont mention incest in Patreon but did here still got their Patron shut down, someone either followed them here, or reported them to patron...
This one makes sense for it to be incest, as I have grown tired of saying... Otherwise Lizzie not wanting to fuck Brian makes no god damn sense, they didnt grow up togeher (if you want to say stepsiblings dont bang either), Phil, Brian's legal guardian adopted him when he was a teenager around 12, he then married Jeane when Brian was late 16... then Brian went to Amsterdam a year later and turned 18 while there, then he came back and started living with Phil, Jeanne, and Lizzie...
EDIT - Another thing that just came to my mind... Jeanne does not really love Phil that much, so why marry him ? Could it be she wanted to get closer to Brian who she was always close to when he lived with his now "dead" parents ? If so why ? Yes you can say she wants to cougar it up, but is that really all there is ? why was she super close to him before he hit puberty then ? Her actions come across as those of a mother that gave away her child but still didnt want to break total ties with him, and still felt affection for him...
