You shouldn't care but it does make a good case study why supposedly "pc" exclusive move to consoles or expand to them.
This is a really weird sentiment.
Most games are multi-platform. Almost NO ONE outside Japan, and motion control based games, makes console exclusive games.
The only time you see that is when console manufacturers PAY to have a game be exclusive.
Bottom line is, unless your game absolutely, positively needs a toy plastic "guitar" or "skateboard", you are being incredibly stupid by NOT putting it out on ALL paltforms - PC, Xbox one, PS4.
This isn't some unique thing in PC gaming. Most PC exclusives, just like the motion contorl games on console, end up requiring specialized input devices like keybaords and mice.
