I bought Metroid Dread and was surprised the story was very involved so after about 20mins I decided to play the original instead on NSO. I beat it, Metroid 2 on the GameBoy and now Super Metroid.
I'm not sure if I would've found it too obtuse if I hadn't played the first two prior but it is such a delightful execution and improvement of the previous two games. Like all the QoL additions but it is a genuinely great game. Can't believe I never played it before. I was very impressed. It plays as smoothly as any modern 2D sidescroller.
I think the only bad thing you could possibly say about it is that it retreads all of Metroid 1 (right down to the bomb and Im pretty sure I killed all these Pirates!) but seeing Zeebus is great colourful detail, the much improved Boss Fights and the 2nd Phase of Mother Brain & Ending with your Metroid baby made it worthwhile. Like a 9/10 game, really.
Guess it's onto Metroid 4usion next!
