Metroid
Samus Aran’s story is probably the darkest of any of the games we have listed here, which makes adapting it into a hypothetical animated feature film a bit more complicated. Metroid games are often isolating, with its heroine off on some space-faring mission by her lonesome. A movie that captures that essence would likely be more along the lines of Alien than something comparable to The Super Mario Bros. Movie. Damn, I’m actually really into this idea but it will never get approved by Nintendo.
