EA Sports MMA
Here's another silly instance of bizarrely tiny things in video games leading to entire bans. This one is mostly the fault of the developer however, quite honestly. EA Sports MMA was banned in Denmark because of its use of energy drink ads within the game. Rockstar energy drink's logo is on the mat during bouts sometimes, and the logo also appears on the end-match stats screen. This is illegal in Denmark, so the game was banned. EA never bothered to edit the game, so EA Sports MMA just went down in history as a game not sold in Denmark.
