For the third week since its launch, Fall Guys: Ultimate Knockout was the best-selling game on Steam.

The title, from developer Mediatonic and publisher Devolver Digital, was released on August 3rd and has been a hit. Within a week of its launch, it had sold more than two million copies on Steam alone. The game's cosmetic pack was the fifth best-selling title of the week.

Second place goes to the latest entry in Microsoft's Flight Simulator series. It's the first brand new title in the franchise since 2006's Flight Simulator X and as a result, there's a lot of pent up demand.

Innersloth's Among Us rose one place to No.4 this week, while Risk of Rain 2 dropped three positions to sixth place. NBA 2K20 from 2K Games took the No.7 spot thanks to a 92 per cent price cut on Steam. The basketball title comes in ahead of the recently-released sequel to popular roguelite title Rogue Legacy. Rogue Legacy 2 has been released into Early Access.

The perpetually-popular Grand Theft Auto V came in ninth place, while indie title Spiritfarer rounds off the charts at No.10. The game was featured in a recent Nintendo Direct broadcast, so received a lot of attention as a result.
