I don't mind the "toggle switch".
Persistent gore in DA2 was turned off. and never got to head shots in ME3... probably due to my combat style.
On strong language.
Here, is where we diverge somewhat. The use of such colourful metaphors may be part and parcel of the character's personality.... like the crusty old sea captain. Apply the filter and he no longer is crusty. You effectively eunnuched him. If the writer is creating this crusty old goat it's for a purpose. The language on/off flag is the equivalent of telling the writer the kind of character the sea captain should be.
See the problem?
On nudity
Simple enough to turn off in the initial game design by eliminating key romance choices early in the game. The romance branch would never take place, after that. Something very similar to the Leliana romance in DA:O. That one I had to search for it.
A tad of a problem remains, however. Again from the writers story telling perspective in an adult world. We see the PC and co. entering a bar with lovelies on the job and you have a mission to complete. Yes, you can choose to walk out and forfeit the mission. It may be an innocuous one that turns out it was critical later on in the game.
My point, here, is that even when you actively avoid such encounters one can appear casu consolto .
I suppose hitting the ESC key to bypass the cut-scene is what you want.
On gore
Interesting that violence and killings is acceptable but gore is distasteful. The first two should be distatsteful as well. Placing a veil over one's eyes to hide the deed somehow makes the deed "cleaner"? However, I must say that this level of realism is unnecessary. A simple on/off flag should come to your aid.
After all is said and done Bio takes our ideas and applies this filter:
1. How much time will it take to implement?
2. How many resources does it take to do?
3. What is the value to Bio?
The last one is interesting.
