Physical Shipment
When you select this option you can use our digital download option to get the game right away and start playing. Then have a boxed copy of the game shipped to you as a backup for permanent storage. With a backup, you'll be prepared for whatever comes your way-whether it's a system crash, a computer virus damaging your files or the software simply no longer functioning as it should. You will be billed to have the game shipped in a printed DVD box with a printed DVD and your serial number.

Yeah, but clearly said no standalone version for Broken Arrow because it's using steam MP. So that does not apply to BA.

You receive both a Steam Key and the game files from Matrix, which are stand alone

It'd still be always online, including the single player portion.

You bought it? Because there website is saying there is no standalone version.

If you think of it as a streaming title, i think you are wrong
I personally i have totally no interest in playing rts titles
