Since Germany is quite strict on ratings, after paranoia over violent video games, a number of the GTA games (since GTA III) have suffered cuts or edits. Some examples include: the removal of blood, pedestrians no longer dropping money when killed, no headshots, some missions removed, some weapons missing or lack additional functionality.

Additionally, in GTA IV, several background characters can be heard saying German phrases like "Scheiße!" (shit), "Entschuldigung" (excuse me), "Er hat eine Waffe" (he has a gun), "Er will mich töten" (he's trying to kill me), "Was wollen Sie von mir" (what do you want ?), and "Gehen Sie!" (Go Away !).
