Evony, an online city-building game that is widely known for placing half-naked women into its web adverts, recently put a commercial during the National Football League's finals to attract more gamers.

The free-to-play game's controversial ads, showing female cleavage, can often be seen in Facebook sidebars. Moving from placing women's half-naked images to get the attention of players to place a commercial during the NFL's finals surprised many.

Many viewers said it seemed strange for a game company to go from placing ads on Facebook to a $5 million Super Bowl commercial.

In the coming months, a number of game publishers are going to publish their potential blockbusters like Horizon: Zero Dawn, and Tom Clancy's Ghost Recon: Wildlands, and Mass Effect: Andromeda. However, commercials for those games will likely not be releases during the Super Bowl.

Like any other game, Evony is always in need of gaining new users as each and every new user will generate in the range of $1 to $2 for the company. But, when the potential of gaining new players on Facebook by alluring people with half-naked images of women dries up, publishers have to amp up their marketing with efforts like the Super Bowl commercial.
