Overwatch has become the 64th console, PC or mobile game to generate $1 billion from in-game spending.

That’s according to the latest global digital market report from Nielsen’s SuperData, which says the hero shooter reached the milestone in June.

It is now the sixth Activision Blizzard IP to top $1 billion from in-game spending, following World of Warcraft, Call of Duty, Destiny, Candy Crush and Hearthstone.

SuperData’s report also said Crash Team Racing Nitro-Fueled enjoyed the second-best launch month of any console racing game, behind The Crew 2.

The market research firm estimates Activision’s racer sold 552,000 digital units worldwide last month despite not launching until June 21. Sony said the game topped June’s European PlayStation Store chart.

VGC said the game is easily the best multiplatform kart racer in our Crash Team Racing Nitro-Fueled review.

SuperData also said June was Rainbow Six Siege‘s best month for monthly active users and sixth-best for in-game spending, driven by the launch of the Operation Phantom Sight update.

Publisher Ubisoft said in May that Rainbow Six Siege had generated more than €1 billion in cumulative net bookings since its December 2015 release, with the game seeing a 40% year-on-year increase in its player base to over 45 million.

SuperData said worldwide digital gaming revenue in June increased 2% year-over-year to $9.2 billion. League of Legends, Fortnite and Honour of Kings were the top-grossing PC, console and mobile titles respectively last month, just as they were in May.
