The answer is "Mario", by the way

Crunching numbers from financial reports isn't just for accountants and financial consultants: when a company like Nintendo releases its figures, even the humble gamer sits up to take notice. A list of the top-selling Nintendo games for the past financial year, then, is like sweet nectar to numeric nerds.

The top-selling DS game from Nintendo last year, to nobody's great surprise, was Pokémon HeartGold/SoulSilver, selling 8.4m copies worldwide. Follow-ups on the DS chart, however, were older titles: New Super Mario Bros., Mario Kart DS and Pokémon Platinum.

Wii software sales, despite generally recognition as slowly fading out, eclipsed the top fifteen DS sellers easily. The evergreen Wii Sports came out on top with 17.7m copies around the globe, with its sequel not far behind on 16.1m and manic multiplayer romp New Super Mario Bros. managing 14.7m worldwide.

One view for the gulf between software sales has to be the DS's piracy problem, which surely accounts for millions of lost sales around the globe due to the sheer prevalence of pirate devices. The console's age may also account for its dwindling sales, with some titles on the list as old as the machine itself and the law of diminishing returns well and truly kicking in.
