Fortnite has all the kids flossing but Type-Moon 's 120.4 billion yen (US$1.1 billion) megalith Fate/Grand Order is the center of the gaming conversation on Twitter. The social media service announced the top tweeted about games in 2018 on January 22 and among the 1 billion game-related Tweets worldwide, Fate/Grand Order was at the top.

Fortnite was second followed by Monster Strike , Splatoon , and PlayerUnknown's Battlegrounds . Also in the top 10 was Granblue Fantasy , Ensemble Stars! , Super Smash Brothers, Overwatch and Final Fantasy .

Japan tweeted the most about games followed by the U.S. and the U.K.

Fate/Grand Order may be the center of discussion but even with its US$1.1 billion in earnings, Fortnite still brings home more bacon. Epic Games, the creator of the FPS-base building hybrid, earned its own US$3 billion in profit last year. Fortnite's worldwide popularity raised the developer's value to US$15 billion.

The children's manga magazine Coro Coro Comic added a Fortnite -inspired manga to its line-up on December 29.

Aniplex released the Fate/Grand Order smartphone game in Japan in summer 2015. The game received an English release in the United States and Canada in June 2017. The series has spawned numerous animated projects, including an upcoming TV anime adaptation and two-part film project.

Although the game is free to play, Fate/Grand Order notoriously makes a lot of money through micro-transactions, earning an estimated 9 billion yen (US$82 million) in September 2018 alone.
