I really need to play Z.O.E sometime but I’ve become picky due to time constraints. You will love the adventure series and I have Arkham on PC via steam, probably the best comic book game ever made.
If we’re also counting length as difficulty, then Star Ocean should also be considered. 600 - 1k hours for all those battle trophies? N-no thank you. ;_;
I haven’t played it myself but P4A’s score attack trophy looks pretty difficult. They removed the 2nd controller retry trick and unlike any of the other arcsys games, you need to beat it with all characters this time. Catherine’s Babel mode & Battlefantasia’s parry trophy are also pretty djfnsbrgbsfgbskdgsd.
