That's an important distinction because that means if you go to an unmanned kiosk, say, at a train station where there are only
machines and no attendants, you can
still buy a
ticket using your Barclaycard.
Regardless, the controller
still probably isn't for every game and a mouse / keyboard combo may
still be your go - to but the option to pick up a nice Steam Controller is
still appealing and will no doubt
still be a hot
ticket when it releases later this year with the Steam
Machines and Steam OS.
