I thought the story in ac Odyssey was very unique with how it prioritized the morality of the time and contrasted it with our modern day morality, and I spent plenty of hours really enjoying that world. Probably my favorite large open world to date (but that is entirely personal preference). I do think Mario kart 8 is the best kart racer ever, and definitely deserves to be on the list for that alone.
As far as I can tell from reading your telling, he has a history of committing violence against women and lying about past events. I hope you recognize this as dangerous.
This doesn’t mean you can’t try to help him, but understand that there are risks.
