A few years ago, I would spend anything from 6 - 9 hours playing video games when I was not only streaming but also creating video game content too. As much as I do still create video game content, due to my line of work now, I don't play for half as long as I used to.
I would say now that I play anything from 1 - 3 hours per day, and sometimes I do not play at all on some days.
