I think that's more a problem of not having a character properly, but agreed. The people who are submerging themselves so completely in this fantasy that it seems as important (or really freaky, sometimes more important) than real life are definitely some creepy peeps. And this comes from someone who has admitted pretty up front to using some of my games as a meansof escape from my RL illness this past year and a half. ^^ I think there's always a certain amount of escapism in certain things-- books, movies, and sure, RK-- but it can't become as important as all that.
Maybe one way to cut down on some of those problems would be to make the game environment even more far fetched? Less realistic? Not that I'm saying RK is realistic. :s
