True, but Google owns YouTube and whatever amount of cash YouTube make, it goes to Google, in 2006 Google pulled the plug on YouTube and decided to buy it.
Either way it still is same price, just like 50 bucks a year would equal 4.20 bucks a month (I think)
Yes, they could do that, but if they play their cards right and know what your doing and make some big cash, you really wont need to be charging people as much.
I dont really get why MMO games need to charge monthly fees, the Stock Market can make you look pretty rich financially, but if you decide to hike up or keep prices the same while you make money with the stock market, you have no god damn brain and are just trying to look rich.
