It's being a couple of weeks since I've finished this game and it does not get out of my head.
I've always enjoyed Castlevania and games which can be referenced as Metroidvania, but for some reason I've never got interested in playing Metroid, maybe because I was a Sega/Sony kid
But some weeks ago I was looking to play something "new" and was not in the mood for the vampire franchise, so I tried my luck and went to play Super Metroid with basically no expectations and suffice to say it blew my mind.
I was really surprised that it had almost everything a Metroidvania has and one generation before SOTN, I didn't expected this from a 16 bit game and I say this having owned Video Games since Atari 2600
I don't have much to add but if you are into retrogames and for some dumb reason, like mine, you still haven't tried Super Metroid, than please give it a chance.
The movement mechanics are faster in Dread, but that doesn't mean they are better. Super Metroid offered button remapping, a feature that even modern games sometimes fail to provide. Some technical aspects allowed for real creative sequence breaking that is simply unrivalled in nearly every other game in the 2D sidescroller action adventure genre.
Dread also has a pretty severe linearity rivaling Fusion and Other M. Super Metroid still beats Dread. Super Metroid is timeless, nothing about it is dated except for maybe the music being MIDI based. Everything about the game combines into a single cohesive whole that modern games still attempt to emulate, with varying degrees of success.
