Battlefield 3 sold over 10 million units.

[Googolplex]

Need For Speed: The Run uses Frostbite 2 engine.
I mean what a difference of sold units. Where Amnesia is a better game than BF3 and sold much much less.
But BF3 is even good, very realistic and you felt like you are in a real war. Both games are good in its own way.
