15 years ago I lost to Joker on the final battle of Arkham Asylum and never played it again. It was just too hard is all. I couldn't do it. I fucking failed. This ate away at me for years.
Last year I finally replayed Asylum and actually finished it and then went on to the other games.
>Arkham Asylum - 100% without guides, plus all predator and most of the combat challenges (you know the one that's missing).
>Arkham City - 100% without guides, all challenges for all characters (yes even Joker's Carnival).
>Arkham Origins - 100% without guides, all challenges for all characters.
>Arkham Knight - 100% without guides, all predator challenges for all characters, only missing some of the combat and Batmobile challenges. Will eventually finish them.
Feels good, man.
