there are over 130 million DS in the world. There are 43 million 360s. That's 3 times more DS handhelds. Plus, Reach costs at least 60$, because there are the 80$ and 150$ editions. Pokemon is 30 or 40 dollars. So yeah Pokemon might sell more, but Reach has made more money because it is more expensive, and it has a larger install base, i mean already 10% of 360 owners have Reach. Pokemon has to sell 13 million to reach the 10% mark. So basically, pokemon doesn't beat halo by selling more. Numbers aren't everything.

What about if Pokemon production costs are less than Halo Reach? Some developers and even Nintendo have said that they need less copies sold on Wii to make  profit if you compare at HD consoles. Same DS vs HD.

About the second, The Legend of Zelda The Wind Waker sold 4.4 mill in a install base of 22mill Game Cubes. 20% of the GC owners have it. So, Wind Waker made more profit than GTA:San Andreas that sold over 18mill on PS2 with a 15% mark?
