Remake the whole game... Why? All he needs to do is change the mother to the classic landlady and remove a few things, etc etc etc. But then again he would probably do it cuz hes milking this game for every cent he can get. Hes been "making" this game for years with so little content, I stopped supporting LP cuz it takes way to long for a update, LP is on the same level as ISCTOR.L&P doesn't distribute AWAM on Patreon. He's offering DoL(Decisions of Life), a heavily altered and crappy version of AWAM so not to get in trouble with Patreon. His patrons are provided with a link to his website where they can access the real game.
As for Steam, he would have to remake the entire game basically. Remove son/daughter relationships, remove illegally used assets (brands such as Coca Cola & Pepsi, several clothing brands and atleast one hollywood movie scene), remove or heavily alter the school setting, age (visuals) of several characters...and so on.
