Just watch it in the breakroom or somewhere where it doesn't disturb others. At one previous employer, they reserved a big conference room / auditorium and got food, like a mini team building event. At another a bunch of people just went to a bar en masse. If you can't take 90 minutes out of your team's schedule, or if it's considered OK to just blast the game in an open-office, there's something wrong with the work culture IMO.
