To the surprise of literally no-one, Playerunknown's Battlegrounds sold five million copies during the month of October.

That's according to SuperData Research, which places the game as the second highest-grossing PC title in the world for the month. First place goes to - of course - Riot Games' insanely popular MOBA League of Legends.

We don't have much of an idea how much of a gap exists between the two. League of Legends is free-to-play but boasts 100m monthly active users. Playerunknown's Battlegrounds is premium and at last official count has 20m players, though that figure is likely closer to 25m by now.

That said, Epic's free-to-play battle royale game Fornite had more users in October then Playerunknown's Battlegrounds. 

Premium PC purchases saw a 28 per cent rise in revenue for the month thanks to Destiny 2 and Playerunknown's Battlegrounds continued mission to take over the world.

Meanwhile, the research company reports that South Park: The Fractured but Whole, Middle-earth: Shadow of War and Assassin's Creed Origins generated a combined $160m in revenue.
