Costumes and cosplayers inspired by video games were in abundance inside the Phoenix Convention Center's South Building during Game On Expo 2017. Folks wearing outfits and get-ups based off such popular games as Overwatch, Mass Effect, and League of Legends were all in attendance at the three-day geek event, which ran from Friday, August 11, to Sunday, August 13.
