You don't have to know anything about video games to enjoy this insane video of the most ridiculous horse race ever. I learned nothing about the way the game works, or even what the point is, but I was riveted. A narrator shows his buddy what the game is about, and he reacts about the way you would if you had no language filter. In other words, NSFW language.
I'm going to go to Japan one day, and if the actual horse races aren't like that I'm going to be disappointed.
