My many problems in RPs:

1.	Me, Myself and I: Rather it be the character or the actual person, this type of personality simply kills me. For characters, well, I simply cannot grasp the idea of how this kind of character is even possible to RP. What I mean by this is that everything revolves around themselves and do not add any interaction to other characters OR everything that happens IS the character.

PS: I have had it happen too often

2.	Unsocial Characters: This sounds stupid, by it is a little like point 1. If I have to force my character to interact in any way, shape or form, well, it is going to piss me off more than anything else.

3.	The GM that draws a story and you simply walk in its steps: This… THIS… I am here to have my characters develop in a WORLD, not be an "NPC" In an already written story.
