While Nintendo’s sales in the US haven’t been up to par, they continue to dominate in their home country. According to a statistics chart by Enterbrain and Famitsu, Nintendo scored 27.8% of all software revenues in May. Its three biggest sellers were Mario Party 9, Fire Emblem: Awakening, and Mario Tennis Open.
Capcom was a close second with 26.8%, as their new title Dragon’s Dogma has become increasingly popular among Japanese gamers. None of the other leading Japanese companies did nearly as well: Namco Bandai got 12.2% of revenues, Konami had 4.3%, and Square Enix had 3%.
It should also be noted that Nintendo did just as successfully in April. Hopefully this is a trend that will continue through the summer and beyond. Who knows- once bigger titles are released, maybe American sales will catch up?
Here is the Famitsu chart showing Nintendo’s sales:
