Nintendo. That is all you really need to know about this list before you look at it. 6 of 10 of these games are Nintendo titles, the rest mopped up by Square Enix, Capcom and Konami. Metal Gear Solid Peace Walker still can't top Dragon Quest this week, Mario also has two big titles in the top 5, with Mario Kart having a really strong resurgence of sales in Japan recently, not sure why. I was under the impression that everyone who had a Wii in 2008 had to get Mario Kart Wii... It was one of the strongest titles of that year on the Wii. Either way, Pokemon Heart Gold and Soul Silver versions re-enter the top 10 again this week as well. Full list below:
