do stadia games cost money?
There are two levels of membership: Stadia Pro, which is paid for, and plain Stadia, a free access plan. Stadia Pro membership costs £8.99 per month in the UK, $9.99 per month in the US. That gives users up to 4K HDR gameplay and 5.1 surround sound. However, you still have to buy the majority of games on top.
