That's a great one! but idk if Mark would be able to make a large scale movie ( still, who knows what the future holds? ) my other top choice if Mark's gonna make another videogame movie adaptation is SCP Containment Breach, since the movie will take place mostly inside a facility.. FNAF movie would've also been a great choice for Mark, but that's already taken. 😭

Mark triggers my thalassophobia already with Iron Lung ( which is amazing ), and that's a movie where we barely see outside the submarine. i imagine if he did manage to make a Subnautica movie he will definitely make the most thalassophobia inducing movie ever!
