I think Notch is one of the few to handle this well. He supports other indie devs that look promising rather than trying to bottle the lightning a second time.

Something else rather important to consider is Mojang has (had?) 49 employees. Not 800 at peak like rovio, not 4900, not even 490.

One is an insanely complicated 3-d cad physics rendering simulator.

The other, the one with 20x the number of employees, is 2-d sprite based bowling with gravity.
