We've talked about Mary-Sue characters before and had some kicks while doing it. For those who don't know the term, it refers to creating a character using stereotypical and unoriginal ideas (like being an orphan, having been possessed by a demon, have deep eyes filled with a hidden sorrow, etc.). Check some descriptions in-game and you'll probably know what I'm talking about.
Well, I've noticed that even when we don't have any Mary-Sues in our event parties, we do have a Mary-Sue presence of some sort that tends to re-write the events and plots to meet that stereotypical scenario that Mary-Sue really enjoys. It's like players are already expecting these situation and they sometimes blatantly ignore what they have in front of them or what they know (or should know) about the world we play in.
Let me give you some examples:
When you see a GM guard your first reaction is:
1) He/She is there to protect citizens and deserves respect.
2) He/She is probably corrupt and I will prove it.
When you saw a riverling for the first time you:
1) Charged immediately because it must be a monster.
2) Kept your distance since you knew they could be quite dangerous.
When you are offered a taste of a very strange looking and smelling dish your reaction is:
1) Yummmmm! It's delicious! *stuffs his face*
2) Er... *grabs a big piece of bread and dips the tip very slightly into the concoction, smiling nervously*
When you see a wizard bringing a pack of ulbers to attack Hydlaa your reaction is:
1) I must join him! He has to be fighting injustice.
2) He's attacking my city, I must help the guards!
When you (or if you) are placed under arrest for a misdemeanor like wielding your weapons in the city, your reaction is:
1) This is proof the guards are corrupt!
2) Please, let me out. I won't do it again...
When you hear a man was sentenced to true death by the Octarchy, your reaction is:
1) Booohhh, criminal! *Tosses rotten fruit at the prisoner as they are dragged to their execution*
2) He must be innocent! Let him go! *Stands in front of the guards demanding a fair trial*
When you hear that the Octarch has decreed that there will be zero tolerance for criminals, your reaction is:
1) I must fight oppression and for our civil rights! Flower power!
2) About time! The fights in the tavern are getting out of hand.
See my point? Sometimes, there are corrupt officials in the government. Sometimes, innocent people are sentenced to death. Sometimes, you should attack first and ask questions later. Sometimes, but not always. So please keep that in mind and most importantly listen. You won't get it right if you don't. It doesn't mean that GMs will force a script on you so that everything plays out as we want, but we do expect outcomes to be logical and for that, players have to stay within settings and drop some of the notions that they so eagerly and inaccurately apply to every situation they face despite the facts.
So please, keep this in mind and resist the urge to Mary-Sue the plot, be it a player or GM event. Remember that what you believe in and your own experiences are not those of your characters. In the end it is entirely up to you how you want to play your character but, as more content is developed and settings get to be more specific, those elements should be incorporated to your RP. Otherwise, you won't be making much sense.
