Let's get started then.

What is the giant's house like?

(Note: type may also effect the characters' object interaction and also the character of the giant himself)

- Cave: the giant would be barbarian or primitive. A cyclops might fit as well.

- Roman Villa: the giant would be or dress like a Roman.

- Castle: This is variable and the giant could be of any type.

- Modern: The giant dresses and/or lives like a modern person.

Plus if none fit these categories, make one of your own as another choice.
