No, it wouldn't qualify as a genre any more than cartoons or live action would. It's a classification of video entertainment, needing certain requirements to be met for an video to qualify, but genre is a separate consideration entirely.Is anime a genre? not that I love anime, but it is a pretty versatile genre if it is one. otherwise I guess I would have to go with comedy.
It was...unexpectedly short? I was thinking more along the lines of "Xenomorph" or "Xenophile" or even "Xenobiology". Googling your response, it seems you were referencing the Warhammer 30K series?..s! Burn them in the name of the Emperor!
