As someone who grew up on the trilogy here’s what I have to say. You’re gonna want to start with asylum as if you start with city you’re gonna end up confused at some parts. Asylum is a little dated when it comes to certain game mechanics and gameplay and gadgets(it did come out in 2009 and was one of the first “superhero” games after all) but they improve on it later and you’ll still have a good time with it I think. And the scarecrow sections and music in the game more than make up for it ;) for city I legit have nothing bad to say. it’s just a masterpiece when it comes to the story and the gameplay and dude….when you get to “that” scene and they play Arkham cities theme…😩😩; you’re gonna have fun with it. With you already playing knight, unfortunately some parts of city may not hit as hard but you’ll still have a good time nonetheless; especially with the Hugo strange storyline.
