I want to install the CK (no, I am not certified nuts, although this decision may lead to that)
But I only want to install on one machine - Is that possible, or is it like the DLC Hi-Res packs where you cannot decide which machines get it; They all do because steam just goes ahead and dumbly installs on all of them ?
I am being cautious (once bitten twice shy after the DLC), because I do not want to introduce another bandwidth hog on all machines which is irreversible without a support ticket routine with valve to get rid of it afterwards.
