I am finally playing Cognition, it is weird to hear the lovely Raleigh Holmes from Scarlet Furies swear, but so far it does not bother me like it did in the Longest Journey. So I guess it really depends on the game, the context and the circumstances. This said, why swear in adventure games when there is no need to? I would prefer not, but I can live with it.
Oh, and that comment in Still Life where she says that she loves what they've done with the place, while it is a wreck, I thought was very funny. I enjoyed that comment, funny how we all react differently to different things.
