What's the deal with the rpers who play on LJ? I've seen some groups that are all about this, and seen a number of rants about people being quite rude in such games, but I don't understand it. How does one make a character? Are they all like based on fan-fic? What's a Mary Sue (I know what it means in fan fic, but how does one make a 'Mary Sue' character)? What's 'godmode'--again, I know what it means in a video game, but how the heck does that work in an RPG? I mean, you can't just SAY "BAM! BAM! Two shots to the heaad!"--and the person dies--can you?
Is there anywhere I can look that would explain these things?
