As it does every week, game-industry research firm Media Create released its chart of the most popular games in Japan. Ever since the release of the DS, a large percentage of top-20 games have been for Nintendo's handheld, thanks to the brain-training game craze in the island nation.

　　But ever since the Wii was released last year, Nintendo's presence on Media Create's weekly chart has risen steadily. This week, the Mario Factory achieved total dominance, occupying the top 21 slots on the chart. Four of those were Wii titles--Super Paper Mario (2nd), Wii Sports (3rd), Wii Play (5th), and Big Brain Academy: Wii Degree (7th). The rest, including top title Final Fantasy XII: Revenant Wings, were all for the DS.
