Ohhh, this will probably be a controversial take, but I am going to frame if to “most disappointing” instead of least favourite.

Batman Arkham City.

Firstly, it is still a great game. I am not stupid enough to say it’s bad. And it is better than Origins and Knight.

But, Asylum is such a beautiful and intricate game with some of the best level design. It is an almost perfect Metroidvania. And then they jumped to the open world for the rest of the games.

That jump, doesn’t particularly add anything, and while Gotham looks great, it is mostly empty and skipped over as you glide and hook to the next indoor section. Outside of some challenges and riddler trophies, it actually is just terrible padding of low level mobs for the most part.

The reason I chose City over knight is precedent, that first jump to open world for me really reduced how much I was invested in the world/areas of the game.

I still love it, and the improvement to combat and gadgets are great, but Asylum will always be king of the Batman games(City is a close but disappointing 2nd)
