I've worked at a bunch of places with video games in SV. Most of the time it's barely touched.

Meals is what really determines how long people stayed. Sometimes 3 people would play video games. Sometimes a team creates a lunch time card game routine. Some teams really love foosball or whatever.

If a place didn't serve 6pm dinner, people tend to leave before dinner time since they got hungry. If they served dinner, then they consistently stayed until dinner time. If dinner was too late like 8pm, then they might as well of had no dinner for most employees.

10am-10pm places develop often because it's a small startup, and because normal commute hours are horrible. I don't know many people although who actually works anything near those 12 hour days.
