Enterbrain hinted at as much in sales data released earlier in the week, but Star Ocean 4 was the number one selling game this week. Xbox 360 also managed a rarity: topping both the PS3 and Xbox 360.

Media Create's charts, covering February 16 through February 22, have Star Ocean 4 in top with 162,232 units sold. This is the highest first week ever for an Xbox 360 game. The game sold a very high 90% of its stock, suggesting that the sales could have been even higher.

Mario & Luigi RPG 3!!! (Nintendo, DS) took second place in its second week with 61,781 units. Below it were three versions of Idol Master SP (Bandai Namco, PSP). Media Create counts such multi-SKU releases separately. Perfect Sun was in third place with 46,474 units, leading Missing Moon's 39,523 units and Wandering Star's 35,376 units.

A mix of new and old followed. Shining Force Feather (Sega, DS) debuted in fifth with 30,581 units. Monster Hunter Portable 2nd G PSP the Best (Capcom, PSP) maintained its seemingly permanent place in the top 10 with an additional 17,775 units. Sacred Blaze (Flight Plan, PS2) debuted with 17,586 units, giving the PS2 a rare top 10 entry.

Closing off the top 10 were two PS3 titles. Street Fighter IV (Capcom, PS3) placed ninth with 17,416 units. The 360 version placed at 33 this week. Demon's Souls (SCE, PS3) took tenth with 15,581 units.

Debuting outside the top 10 this week were DoDonPachi Black Label Extra (5pb., Xbox 360) at 19, Dead Rising Chop Til You Drop (Capcom, Wii) at 21, Keroro Gunsou Gekishuu Dragon Warriors de Arimasu (Bandai Namco, DS) at 22, Play on the Wii Metroid Prime (Nintendo, Wii) at 26, Sonic World Adventure (Sega, PS3) at 43, and Clear (Sweets, PS2) at 44. The Xbox 360 version of Sonic did not place.

While Xbox 360 lead the way in console hardware, it wasn't the best selling piece of hardware overall. That honor went to the DSi once again, which sold 41,839 units this week, down from last week's 53,483 units. DS Lite added in an additional 9,975 units, down from last week's 12,484 units. PSP also saw a drop from last week's 34,256 units to 29,552 units.

Xbox 360, with sales of 25,334 units, saw a nearly three-fold increase from last week's 9,833 units. PS3 and Wii both saw drops. Wii fell from last week's 21,016 units to 16,973 units. PS3 fell from 18,656 units to 16,149 units.

Total software sales for the week were 1,067,665 units, Media Create reports, a fall of 8.52% from last week.
