I remember there was this one game called "Petville" (BEST game out there at the time!) I'm sure many of you remember it as well. You get to take care of your own pet, name him or her, feed your pet, clean their house (and your neighbors' houses)...and best of all DESIGN The House your pet lived in. To earn money to purchase the furniture, all you had to do was take proper care of your pretend-pet, and keep their house clean. To earn more $$, you could clean your neighbors' houses, and then from there, you head on over to the stores to start buying the furniture! So much fun. But I remember you could also use your own money to buy the furniture, meaning, $5.00 would = a certain amount of Petville money and then you could really get your house looking pretty awesome. I will admit that ONE TIME I did put in $5.00 of my own money just to buy a few extra things to start decorating the outside patio and pool area. Guilty as charged. Have you ever gotten so involved in a game on Facebook that you started putting up some of your own (real) money to play?
