Methods of acquiring GBP are listed below...

Gifts	Mom does not accept gold as gifts. Gifts must be personalized and thoughtful. Regardless of cost, a gift gives 100 GBP. You cannot give gifts more often than 1/week, resetting at the end of each weekend.
MVP	At the end of each encounter, Mom awards someone an MVP award. They gain 100 GBP. Encounters can include non combat scenarios as well (at DM discretion).
Very Good!	Whenever a family member rolls a natural 20, they get 10 GBP. Randomly rolling dice to fish for bonus points is discouraged.
