Metal Gear Solid 5, FIFA among Facebook's best and most popular games of the year

Facebook has published its overarching year-end retrospective, which finds the social network naming not only its most-discussed games, but crowning several titles as the best of the year.

Topping the list of most popular 2015 games is FIFA 15. Electronic Arts' latest soccer title is followed by Mortal Kombat X, with Fallout 4 and Fallout Shelter sharing the bronze medal in third place.

The full top 10 list is as follows:

• FIFA 15
• Mortal Kombat X
• Fallout 4 and Fallout Shelter
• Batman: Arkham Knight
• The Witcher 3: Wild Hunt
• Metal Gear Solid 5: The Phantom Pain
• Dying Light
• Star Wars Battlefront
• Pac-Man 256
• Halo 5: Guardians

This data was culled from analyzing Facebook posts in an "aggregated, anonymized way," measuring the frequency with which these titles were discussed on the platform, according to the Year in Review's methodology page.

While this list represents an objective, quantifiable ranking of the games Facebook users around the globe shared most often, the site's blog for developers has named several titles as 2015's overall best. This list awards games both made for Facebook specifically as well as those that best use the platform across a number of categories.

The PlayStation 4 received a call-out for its Facebook integration, with the developer's blog praising the console's sharing function. The post also notes that "every 10 seconds, someone new connects to PlayStation with their Facebook account."

Metal Gear Solid 5 was not only a popular discussion topic on social media this year, but received Facebook's award for best game ad campaign. The trailer announcing the game's launch received more than 8,000 likes, and fans shared the video more than 3,000 times.

League of Legends was awarded the title of best overall gaming Facebook page thanks to its growth from 8 million to 13 million likes.

Activision was named by Facebook's developers as one of its studios to watch, thanks to its recent acquisition of mobile and online game company King Digital Entertainment. Activision purchased the Candy Crush Saga developer for a whopping $5.9 billion in early November.

Facebook is not the only social platform to name its biggest games today – YouTube shared a list of its own this morning, with Clash of Clans beating out popular titles like Fallout 4 and Final Fantasy 7 for most viewed gaming-related video.
