As you've seen, Nintendo's 2009 fiscal year results are in. Pushing on from the cash money, let's now take a look at the games: which ones sold, how many they sold, that sort of thing.
WARNING: these numbers will make every "1 million sold!" proclamation from other publishers seem tame by comparison.
The following sales figures are worldwide numbers, and are just for the past fiscal year, so they're only counting sales made from April 1, 2008 to March 31, 2009. Numbers in (brackets), where indicated, are lifetime sales figures.

Pokemon Platinum - 3.75 million
Kirby Super Star Ultra - 2.36 million
Brain Training 1 & 2 - 7.31 million combined (31.12 million)
