For me, that's not the point. For me, it's the fact that there's a trailer advertising the new stages for PC, when they are actually not coming. I wouldn't mind if they didn't false advertise. Y'know?
Look at the second one, not the first. The second one is the same trailer TN released for the PS4 and Xbox One version. I just hope that the stages come in the online patch.
It's subjective if you like the missing contents or less, but it's objective that you are paying for the Steam version the same money as for the PS4 and XboxOne versions including them...
