So, when you're making a character for a story game, role play, script, or generally any written work, you want that character as fleshed out and distinguished as possible; and I'm not talking about making them suffer blindness or have dicks for fingers like a hack. Those are gimmicks, not defining character traits. Obviously it depends on the story you're composing, but the majority of the time writers give their protagonist a disability and tend to think they struck a creative gold vein.
Anyways, A fun exercise I've started doing when drafting a character sheet is to include a set of quirky or specific questions about them. They don't need to be important to the story, or even mentioned at all, but it helps to develop an understanding about the person you're basically fabricating from thin air. Here are some that I've used in the past ^__^ ;
How do they take their steak, if at all?
What's their favorite movie?
Do they have any fears or phobias?
Do they have any scars or marks on their body?
These questions will likely differ depending on the world your story in set in. Futuristic dystopia, Vietnamese civil war etc. What are some questions you guys have used or think would work well? Are there any other exercises or things you try to make your character feel more realistic? :)
