Yeah you can current gen game on even a series s if you don't mind 1080p for cheap as fuck with game pass. (Relatively speaking ofc)
Honestly I still have to give credit where credit is due. As much as everyone's struggling lately, it's the perfect deal 200 dollar Series S on sale or used, and then game pass.
Not sure either. I have a series S, a switch lite and a PS5. Haven't used a Series X yet.
