my daughter is almost 9 as well and i think if i limited her internet/gaming time that much she just might stage a mutiny. she plays her electronic stuff prob that much a day. she is very well behaved and does exceptionally well in school. i dont think gaming is the prob, but rather parents who dont properly parent outside of them. if your son is well behaved its because you are a good mom, i dont think it has to do with the restrictions he has on gaming
