Chances are if you don't understand the success of Armada then you are not seeing it from the perspective of a typical male child.
There are HUGE amounts of marketing research that go into understanding/exploiting the child market. McDonalds and Disney are notorious for it. Hasbro most probably does it too.
Male children are stimulated by bright colors, fast movement, loud noises, catchy music and violence. Transformers offers them that and then represents it in the material form of toys. In western cultures many families with children have both parents working creating greater income to spend on their kids who are being raised by brightly colored talking characters on their televisions.
EDIT:
Yeah, that's the one.
