In Germany, until recently, you had to import games dealing with violence and/or the Second World War if you wanted to play the original version. You will not find swastikas in the German versions of call of duty, medal of honor, wolfenstein, blood rayne, übersoldier etc., sometimes animations like the Hitler salute or even the beard of Hitler were removed (Wolfenstein The new Colossus). Here one does not play against Nazis, but against "the regime". Also the level of violence would often be drastically reduced for the German audience, so in soldier of fortune 2 there are no human opponents, but human-like robots. Often the ragdoll model or blood splashes and textures are missing, in unreal Tournament 2003, for example, green instead of red blood splashes.
Even in the last of us the gore effects were removed in the ps3 version in multiplayer.
There also is no gore in fallout 3 for example.
Thank god this has improved in the last years, the level of violence is now often completely present and with Wolfenstein Youngblood the first game in the international version (with swastikas) was released and could be sold officially.
Things are going uphill.
But until a few years ago I had to import many games, often from Austria, because some titles were not even released here, like Gears of War, Dead Island or Dying Light. My last import was Wolfenstein II The New Colossus due to censorship.
