Hello dear RPS,
although I've been reading RPS since 1873, I didn't feel the need to register and comment/discuss. However, after seeing the recent article about CD Projekt, I felt obliged to register and at least slightly defend my favourite developer. So let's get to the point, which is the fact, that CDP is not the only company that is "threatening alleged pirates". As you can see in a German article about this case, as far as google translate isn't mistaken (and I'm almost sure it's not), it seems that there are more companies that use such methods:
Rechteinhaber: CD Projekt RED Sp.z.o.o.
"The Witcher 2: Assassins Of Kings" (Computerspiel)
Rechteinhaber: Firma Techland Sp.z.o.o.
"Call Of Juarez - Bound In Blood" (Computerspiel)
Rechteinhaber: Koch Media GmbH
Der große Crash - Margin Call
Deus Ex - Human Revolution
Batman: Arkham Asylum (Computerspiel)
Just Cause 2 (Computerspiel)
Kayne & Lynch
Supreme Commander 2
Ship Simulator Extremes
