While I'm not bothered by cussing and nudity in video games I feel that it should be situational and appropriate.
Gratuitous sex scenes with no purpose other than nerdboy fodder (A la the first Witcher game) = no.
Sex scenes that show far too much for a video game when a simple fade to black or tasteful scene would have sufficed? (The Witcher 2, doggy style in the elven pool anyone?) = no.
Same with the cussing. While I agree that it makes a situation seem more real (I mean who, when stabbed in the foot, would say "Ah DARNIT!") I also feel that putting modern slang into an otherwise fantasy world is a bit weird. It's the one thing that stuck out to me in DA:I in fact.
Either way, a filter for cussing and option to skip nude or sexual scenes would be good settings options for people who prefer that. I would likely not use it but if it makes a great game enjoyable by even more people, why not!?
