Uhhhmmm....Steam is not that right? Where do I put steam DRM? Will there be an extra field?

I think that Steam DRM can be considered as physical protection because it requires an input which is not hard coded into a disc and is not made available within a package, not like serials for example.

One media which "cannot" be run without an other media.

PX-760A (+30), PX-W4824TA (+98), GSA-H42L (+667), GDR-8164B (+102), SH-D162D (+6), SOHD-167T (+12)

Or you can just rename the field back to normal and tell certain people not to add CD-Checks and DVD-Checks as protection roll
