Battle royale blockbuster Playerunknown's Battlegrounds finished 2017 the same way it spent most of it - at the head of the Steam game ranks.

The title was No.1 for the week ending December 31st, having smashed the 30m sales mark just before Christmas following its PC 1.0 release and Xbox One launch.

Second place went to Grand Theft Auto V after its RRP was cut by more than 50 per cent as part of the Steam Winter Sale. The same applies to third place, Counter-Strike: Global Offensive, whose price was axed by a third.

Meanwhile, the million-selling Divinity Original Sin 2 comes in at fourth place with a slight price reduction as steampunk RPG They Are Billions charts at the No.5 spot with no cut in RRP.

RPG double team Dark Souls III and the Game of the Year Edition of The Witcher 3: Wild Hunt come in at sixth and seventh places respectively, while the double platinum Cuphead returns to the Top Ten in eighth place.

Ark Survival Evolved comes in at ninth, while Assassin's Creed Origins closes out the Top Ten.
