Do you let kids play with games or gaming equipment? Do you let them, but with monitoring? How well do you take care of games and equipment? Myself, I let kids play with games - but they have to be watched like a hawk!
I try to keep things digital these days.This way I can have cloud backup and get the keys restored too. In such case the damage to the laptop and PC can be tolerated. I have seen that to be working out so far. I don't trust kids and so it's often better to have digital downloads.
I want to say it's one to one, but in all honesty I'm a bit fuzzy there. I can recommend JoyFreak's sister site AdminIntel - Admin & Webmaster Resource where there are lots for people of varying degrees of expertise with development, you likely can get a far more precise answer there!
