A lot of people were upset after NIS America announced it had "edited certain aspects" of Criminal Girls: Invite Only for Western release. The "c" word (censorship) was thrown around nobly as it always seems to be when erotic Japanese games are being discussed.
NIS America addressed this in its forum and the editing it has done is downright mild. You can still spank and whip blushing ass-up anime girls to your hearts' content, though you'll have to loop your own sound effects.
"The punishment minigame will remain as is, with a couple small tweaks. The first is that the associated audio will not be present (moans, gasps, short phrases, etc.). The second is that for certain scenes with little to no steam, some steam effects will be added back in to obscure some potentially problematic images. This will be kept to a minimum.
No other scenes or content will be removed. As a general approach, we are being very conscious of the general tone of the game and making sure that we retain the spirit of the story and characters without taking things too far (this will mostly consist of terminology choices and character interactions here and there)."
Just change the terminology and it's all kosher.
And for those of you who think they still rolled belly up on this like freedom hating prudes, according to various rating boards, "these changes would be necessary in order to make a release possible in all regions."
