Yeah...there is a great amorphous money and power element at play with minecraft..that isn't really calculated that is much different than the Nokia purchase (which was M$ ability to control not just the platform but devices as well...perhaps they have learned now that this 1990 agressive business acquisition model of buying everything involved in a process from beginning to end doesn't necessarily work today...)..minecrafts purchase is more akin to the purchase of Skype...but far more intelligent a purchase...the fact it is popular across many devices...apple ....android...the fact the revenues go beyond the game itself...t-shirts and other real ..physical merchandise ....
For the biopsic dissective study alone...it is a most brilliant purchase.
