It's hard to believe Overwatch isn't even a year old. Blizzard announced earlier this month that the hero-centric, team-based shooter is a $1 billion franchise, it has more than 30 million players, and it regularly crosses over into the publisher's other games. Yet it's true--Overwatch won't get to celebrate the anniversary of its debut until later this month. A celebration it shall be. Blizzard announced today that a Game of the Year Edition of the game will debut PC, PlayStation 4, and Xbox One on May 23.
