From a technical aspect, this is the best Arkham game with stunning visuals and the most perfected freeflow combat system in the series. From a content aspect, this is by far the worst - A stupid story with an even stupider ending and "twist." No boss battles apart from the Batmobile tank fights. Shoehorned-in Batmobile sections. Mark Hamill is the highlight, as usual. Possibly the personal biggest disappoint I've ever experienced in gaming.

In its original state, definitely the worst SoulsBorne game, but still very much worth playing if you can't get your hands on a PS5. The prototype for all the greatness to come. World Tendency is awful even when you are able to finally understand it, and that's just one of many crazy negative quirks in the game that From Software thankfully learned from.
