Thinking of starting my first Metroid game, what should it be?

Yeah I think you made a wise choice on Super Metroid if you're just getting into it.

I would say go for Zero Mission, if you intend to play the original metroid in any shape or form. You could play the NES one but bear in mind you're gonna be writing down alot of the passwords or using savestates to get through the game
