What is an All-Star Player Character? It’s a character that has all the tools needed to make him or her as interesting and fun to play as possible. It’s not necessarily an overload of information; just the right amount of information.
When a player writes up a character, it could be just a single sheet with a few numbers on it, several pages of a short story, or somewhere in between. What’s important is that a player gathers just enough information about their character to maximize their enjoyment. Too little information can make the character vanilla bland. Too much information can make the character too complicated to remember.
