I've got some questions about this game.
 

I own this game for PS3 and XBOX 360,PC via steam.

Question 1- The PC version sold on the telltale website is that steam as well or is it different from the steam version. IE acheivements.
Question 2- Will there ever be xbox controller support for PC game. It seems very difficult to run without a joystick.

1) The version Telltale sells has no achievements. Other than that, it is exactly the same as the Steam version.

2) The PC version supports an XBox controller, but not the Mac version.

good job! Quick and to the point.
