While rumors of Hi-Fi Rush and Sea of Thieves coming to other platforms are surprising, it's not something new for Xbox.
In the past, console exclusives Ori and Cuphead have already been released on other platforms, and in 2023, Minecraft Legends appeared on PlayStation and Nintendo Switch. Thus, Xbox publishes games on competing platforms at its own discretion.
It's unclear whether Hi-Fi Rush will be released on third-party platforms, but that doesn't mean other games will follow suit. As the creator and host of the popular channel Kinda Funny Games, Parris, explained, this does not mean that Gears 6 will be released on PlayStation and other platforms.
Hi-Fi Rush will resonate with Nintendo audience, and the service game Sea of Thieves needs players, but Indiana Jones and Gears 6, quite expectedly, will bypass competing platforms.
In 2024, the feasibility of exclusivity is weighed by creators. In recent years, gaming giants like PlayStation have deviated from strict rules, porting many games to PC with varying degrees of success. And only Nintendo remained committed to a single ecosystem around the main device.
