Japan charts: Dragon Quest still No. 1
Peace Walker debuts in second.
PSP exclusive Metal Gear Solid: Peace Walker debuted in second place on the Japanese sales charts for the week ending 2nd May.
Square Enix's monster-collection RPG spin-off Dragon Quest Monsters: Joker 2 took the top spot with 624,000 weekly sales, easily besting Peace Walker's relatively strong 434,000 units, according to data released by Media Create.
Versions of Capcom's Super Street Fighter IV took the third and fifth places on the list, selling 81,000 copies on the PS3 and 28,000 copies on the Xbox 360 in its first week on sale. Last week's top seller, Nier Replicant, fell way down to ninth with only 21,000 weekly sales.
Nintendo's tradition of strong, perennial sellers continued with four games - New Super Mario Bros. Wii, Mario Kart Wii, Tomodachi Collection and Wii Fit Plus - appearing in the week's top 10 sellers.
