There is a huge difference between VMK and POL.
VMK was made to bring guests to the real parks via the children. Of course the adults also enjoy the game.
POL is made to be a pirate game. The only income Disney will receive is from the monthly payments. This income will pay for everything to keep the game fresh and fun.
