I just had an idea for you getting PO.
Buy a USB key!! That way, you won't waste any of your dad's space, and you can just take the PO around with you on the USB!
Just a suggestion, playing video games all day isn't actually healthy, BUT, if space is the problem, just ask your dad for a USB.
Also, then, you can put your school assignments on it, carry data around, etc. Sound good?
