Oh, when it's books it's not ok to edit it for different audiences, but games is another story.
When games as a medium have the power to influence generations and insight wars and riots then maybe but until then yes, the answer to your question is yes it's okay for games but not 'certain' books.
The edits on Walden here (and similar ones on ancient texts) involve tweaking the meaning of the words by translating them into a more modern syntax. The game edits involve less tits/ass in a game. Contact me when a game censorship complaint involves "they lost part of the plot in translation!" instead of "they took out the cute girl's butt slap!".
Has happened plenty of times. You're more than free to google it.
