Metroid 2 turned its technical limitations into claustrophobic feeling. It has aged surprisingly well if you disregard the visuals. I started my Metroids with Prime, but og M2 is the oldest I have actually played through. NEStroid has many outdated features that makes the gaming impractical like starting with 30 health, slow healing, save system, difficulty curve etc. Playing M2 felt closer to Super than NES. The spider ball was also neat. I even liked the experimental soundtrack even though that’s an unpopular opinion.
Super and Echoes might be my favourites as well. Also shoutout to Fusion and Zero Mission. They were good too, although they owe so much to Super.
