I was impressed at how well this 15 year old game held up today! The combat was chunky and satisfying, the performances from the villains (joker especially) were great, and the atmosphere was incredible. There were cool little details that stood out, such as the fact that as the night went on Batman's suit and cape became more and more worn, and I loved that during stealth encounters henchmen became increasingly terrified the more of them batman incapacitated. The sound design was definitely a little wonky at certain points, enemy encounters became a little same-y eventually, and the final battle was underwhelming, but otherwise this was a good time and a good blueprint for the Arkham games that came after.
