@Kestrel It’s definitely a semantic difference, but I also think that it’s an important semantic difference. I think that seeing/using them synonymously can contribute to bleed and to feelings of competition rather than cooperation.
I don’t use CvC instead of PvP, I use it alongside PvP. You can have both on the same game (people working cooperatively OOCly to create a good story of competition between their characters versus people competing OOCly to have their characters win). I don’t even see PvP as a bad thing… it can be really fun sometimes if you’re doing it with folks that you trust. But I do think that it’s valuable to have terms for each, because they’re very different and—to bring things back full circle to the point of the thread—appeal to and bring in players of very different temperaments.
