I never owned a NES, SNES or Gameboy advance, my first Nintendo system was the gamecube (before that I owned exclusively PC, Playstation and PS2). Therefore I only played Metroid Prime on Gamecube when it first came out and much later Samus Returns the 3DS game.

I started playing through the whole series now, since I still have the 3DS game and I can play the rest on Switch.

I played the original two games for a bit just to experience them. The first game has great atmosphere for a NES game. Metroid II doesn't look as nice since it's a gameboy game so it doesn't have the atmosphere, but the gameplay felt instantly smoother.

I'm not going to bother finishing those though, I'll just play the remakes of the first two games and then play Super Metroid, then Fusion, then Dread.
