Oh I think you'll love the first 3, if you can you should look into playing asylum, city, then origins! It's worth it trust me! Arkham knight was so fun, I don't blame you for spending hours on it, it's a really great game! There's a collection on the ps store that has the first 2 games!

I’ll definitely look it up. Hopefully soon they’ll be available on psn+? 🙌🏻
