Why Far Cry have this massive legs?

[Ryng]

Seriusly, i think that after Nintendo games, Far Cry is the game with Most massive legs.

Both Far Cry 3 and 4.

Far Cry 3 is almost not dropped the second week, and it still sell nice.

Even Far Cry 4 have really good legs, UK and Japan chartz confirmed.

 Why this in your opinion?
