I do not think is it because they did it.
It is because they did it though, the branding behind this game will be very big. The characters are already in high demand for other things.
IF Disney does get this right you have to remember they own a shit load of shit
This would open the door to a Marvel game like this, A Star Wars game like this, This will make them LOTS AND LOTS AND LOTS of money is his point.
Disney will do it bigger better and stronger. At least that is what the thought is.
Sure - they have resources and can do it bigger and better.
I wouldn't call it a "genius move to bring in-app purchases to the real world" after it's already been done for years. When someone gives me a virtual reality gamer helmet that doesn't burn my eyeballs out - that'll be the future of gaming.
