To protect the identity of my fellow role-players I will only use the names of characters and not the actual names of the role-players themselves.
The Harry Potter role-play started about two weeks before I joined. So, by the time I joined, the players had already established in-game friendships with each other and I was the odd one out. Yet, I did not join with a defeatist attitude. On the contrary, in my first scene I bullied Ruth and was cursed by Daniel. This brings me to my first point: when joining a windows driven campaign, you have to come with ideas. Yes, there is a Games Master, but the game will not be as fun as it can be if you do not bring ideas of your own.
*Prince was a character who had a harsh home life. His father was introduced in a short scene created by a player, and he was loved. So much so that he became more of an important character and eventually became a major villain for the rest of the players.
*Daniel was a character who was a bit strange. Thus, the players focused on him and to spite the fact he was suppose to be a minor character, he became one of the main cast.
*Chris, played by someone who did not want the character to be the lead character, ended up being the lead character simply through the situations that other characters put him into.
