Interesting. You would think that a top twenty list of Japanese software sales for the first half of 2010 would be filled with titles released in 2010… you would think that.

In reality though, this couldn’t be further from the truth. Less than half of the top twenty games appearing in the list (comprising the best-selling titles for the first half of 2010 in Japan) were released in 2010. The rest are all 2009 releases and older.

What’s more, thirteen of these titles appear on a Nintendo console, with the top-selling title being New Super Mario Bros. Wii. Deduce from that what you will.

To be shocked out of your socks (or not, as the case may be), read through the full list of best-selling Japanese games in the first half of 2010, below:
