"Swearing is a really important part of one's life. It would be impossible to imagine going through life without swearing and without enjoying swearing... There used to be mad, silly, prissy people who used to say swearing was a sign of a poor vocabulary -such utter nonsense. The people I know who swear the most tend to have the widest vocabularies and the kind of person who says swearing is a sign of a poor vocabulary usually have a pretty poor vocabulary themselves... The sort of twee person who thinks swearing is in any way a sign of a lack of education or a lack of verbal interest or -is just a f***ing lunatic... I haven't met anybody who's truly shocked at swearing, really, they're only shocked on behalf of other people. Well, you know, that's preposterous... or they say 'it's not necessary'. As if that should stop one doing it! It's not necessary to have coloured socks, it's not necessary for this cushion to be here, but is anyone going to write in and say 'I was shocked to see that cushion there, it really wasn't necessary'? No, things not being necessary is what makes life interesting -the little extras in life." - Stephen Fry
That aside, I don't mind it, just so long as it doesn't ascend to Rogue Warrior-levels of the words f*** and c*** being used as every other word.
I don't mind, depending on the tone of the game it could actually be considered an immersive factor, but if it is overused like in Prototype 2 where it seemed every other word was an F-bomb, then I have a problem - not because it offends me, but because it annoys me.
It's like having a conversation with someone who is obsessively compelled to use a certain word as many times as they possibly can.
