Zelda, Metal Gear, Wizardry, Faxanadu, Rygar, Ys, Mother/Earth Bound. The list goes on and on. The element of revisiting previous stages/locations to unlock portions you couldn't access earlier on was a basic ingredient of old adventure games.
Spanish wikipedia, while English wikipedia says something else. Did you hunt with Google until you found some lone source citing it as "Metroidvania" just to try get a point across?
I live in a Spanish-speaking country, so Google defaults to Spanish Wikipedia. I forgot to change it to English like I did with my second link for the HN crowd. But you are incorrect yet again. https://en.wikipedia.org/wiki/Rygar ctrl-f "Metroidvania"
My point is that you create a lot of noise when your "corrections" aren't actually correct. It's basically nerd sniping to be wrong on the internet, especially about games.
Yes, I'm contributing to the noise. But I'm correct, so it's okay according to unwritten HN guidelines.
Which other NES or SNES games take place on one continuous map that you backtrack with new abilities to find a way to progress?
Edit: that you wouldn't consider a metroidvania, I mean.
