Interesting. The Aquarius system itself is under Intellivision. Should we add an Aquarius category under Intellivision?
Maybe rename Intellivision Base category to Mattel Electronics with sub categories of Intellivision Hardware, Intellivision Accessories, Intellivision Demo, Intellivision [NA], Intellivision [EU], Aquarius , Aquarius Hardware?
