Great ideas Angel Bun. I just thought of another idea too. Offer the following as choices for personal upgrades:

Piano Lessons - There would be 3 levels of training. Each purchased seperately. On each level they would automatically learn a new tune. They would keep each learned tune and play them randomly when they choose to play the piano or when dropped on it.

Guitar Lessons - Same as above.

Dancing Lessons - This one should be easy because it would just convert to the way the little peeps responded to the radio in VF1. They would find the radio turn it on and dance on their own. It would be nice if they could also listen to music as they did in VF1.

Cooking Classes - This upgrade would change the meal the little person made when he/she made a meal. Anyone who has not taken this class will make the same standard meal. But, anyone who has taken this class will make a new meal. There could be 5 or 6 randomly assigned meals in the upgrade.

So, for example let's say Mom took the class. Now when she makes meals she makes burgers and fries. Everyone else still make the old standard meal. And let's say Dad takes the class as well. Now, Dad makes steak and eggs when he cooks a meal. If the kids are old enough and they take the class, they would each get a different meal assigned to them depending on the next meal assignment in rotation.
