Global free-to-play games revenue saw a 6 per cent increase to $87.1 billion (S$117 billion) last year, with Epic Games' Fortnite ($1.8 billion), Nexon's Dungeon Fighter Online (1.6 billion) and Tencent's Honor of Kings ($1.6 billion) ranked in the top three spots, according to a recent report from data analytics company Nielsen's SuperData Research Group.
Chinese internet giant Tencent also saw its Game for Peace ($1.2 billion) and co-published League of Legends ($1.5 billion) among the top 10 list.
Last Shelter: Survival, which was produced by Beijing-based Long Tech Network Limited, took the 10th place with $1.1 billion in revenue.
According to the report, world digital games revenue last year had a 3 per cent year-on-year rise to hit $109.4 billion, among which free-to-play games spending accounted for 80 per cent of all the revenue, thanks to strong performances from mobile games.
Chart-topping regulars like Honor of Kings and Candy Crush Saga promoted mobile's share of free-to-play income to 74 per cent, said the report.
Besides, mobile games accounted for six of the top 10 free-to-play games by revenue, the report showed. Last year, mobile games earned $64.4 billion.
The premium games market, however, saw a 5 per cent decrease last year to $18.9 billion, since there were fewer blockbuster games launched than the year 2018, the report said.
