The battle royale hype train shows no sign of slowing down with Playerunknown's Battlegrounds and Fortnite generating a colossal $200m in January.
That's according to research specialists SuperData, which reports that the duo made that figure across both console and PC for the month, noting that that Epic's title saw record engagement.
Fortnite is present in the console charts, too, with PUBG absent, so it's hard to get an idea of which is generating more money overall.
League of Legends was unsurprisingly the top grossing game of the month, because, well, it's League of Legends, with Dungeon Fighter Online from Neople and Smilegate's Crossfire taking second an third places.

In total, gamers spent $8.9bn on digital content across all platforms. Premium PC revenue was up 24 per cent year-on-year.
