If and when my kids ever get into video games, there will be time limits on play. My younger brother was/is obsessed with video games, and I remember him playing them from the time we got home from school, late into the night, sometimes all night long. It was ridiculous, IMO. I don't want my kids having that kind of addiction to gaming. Moderation is fine, but definitely not every waking moment. As far as paying for things, I would be fine with them paying for things with their own money from allowance or work (if they have jobs as teenagers), but again, time limits on play would be enforced. They need to be doing other things as well.
