Some believe this is mainly due to the other popular and prospective video game handheld consoles like the Game Boy Advance, Nintendo DS, and PlayStation Portable, all of which have sold far more than the Xbox 360 and all of them are Japanese originated consoles, indicating a nationalistic preference to game consoles. Others have attributed this slow start to titles such as "Dead or Alive 4" and "Enchant Arm" missing the launch date, while others point to the marketing strategy that focused on selling the Xbox 360 as a fashionable item when customers were looking for an affordable or a high performance gaming console. It should also be noted that "ToHeart2 XRATED", a highly anticipated hentai PC port of the PlayStation 2 game of the same name, was released one day prior to the Xbox 360's Japanese launch; this might also be a factor in the console's low launch sales.
