What Is The First Video Game Ever?

Do you know what the first video game was called and looked like? Well, it is still a matter that is up for debate. This documentary by Ahoy goes in-depth into the history of video gaming with a focus on identifying the first video game ever in the world. Watch this very informative video and learn something new (unless you are a video game historian of course). 

What do you consider the first video game to be? I am curious to know what you all think so feel free to leave a comment below!
