Unfortunately, Donkey Kong and Crash are dead.

I am impressed by the ones that are up on all three regions such as: Mario, Pokemon, Zelda, and Final Fantasy. Some others that are impressive are GTA, Sims, and Halo for such a short time to get up that high in US. NINTENDOGS is....WOW

Mario and Pokemon number 1, 2 everywhere =)

The Sims numbers don't match. The Sims franchise has sold over 100 millions copies worldwide.
