Video games are already movies that are video games.

The ending cutscene of Metal Gear Solid 4 alone is a full feature-length film.

(And it’s annoying as hell if you actually want to play a game rather than watch a movie.)

There’s no end to games with near or actually 0 story/narrative.

Games can have a story/narrative without extensive scripted cutscenes! These things are almost entirely orthogonal.
