You keep saying this by merely deconstructing core elements to such a basic level that can fit in just about every game. Like having any "narrative" beyond a prologue somehow meaning it's just like Other M's narrative where Samus wasn't even a silent stoic protag and that was the main issue there to begin with, the different characterization of her. Similarly the issue with having federation interactions in Other M was that they blocked her/the player by simply giving or not giving permission to use this or that tech she actually already had, again a very different approach to merely (re)discovering the tech and then using it as in this and every other Metroid game (even if she some times has to go back to the engineer to integrate it in her suit or whatever, that's still waaaaaay more like the previous games than Other M). And Prime 3 already had more characters and things like that, possibly even more than what we've seen in Prime 4, though it was perhaps more in the beginning of the game than elsewhere (but still also elsewhere) and was still a great Prime game worthy of the trilogy so everything you say is like Other M could be said as being like in Prime 3 instead, oh no, number 4 has elements of 3, who'd have thunk it. While also going back on 3 elements by now having all these different areas but instead seamlessly connected via the desert rather than a spaceship cut scene or whatever else taking you from place to place, oh no, a seamless world, so bad for Metroid, lol.
