It just crossed my mind randomly. It doesn't have to be a whole movie dedicated to gaming. Just a scene where gaming logic or gaming culture is depicted accurately.
Admittedly, it's always weird to come across mentions of gaming I other popular culture. I personally have never been a fan of gaming or anime references in Rap, and seeing it in a movie always takes me out of it. It's just an odd thing to slip into a movie that never feels not forced.
