忍者龍剣伝
"Ninja Gaiden" was critically acclaimed and sold 362,441 copies in North America in the first month of release; however, Japanese sales were poor. Team Ninja released two packs of downloadable content, which were also incorporated into a reworked version, "Ninja Gaiden Black" (2005)"." In 2007, "Ninja Gaiden" was ported to PlayStation 3 as "Ninja Gaiden Sigma", with extra content and graphical improvements; this was released on the portable PlayStation Vita as "Ninja Gaiden Sigma Plus". "Ninja Gaiden" was followed by "Ninja Gaiden II" (2008) and "Ninja Gaiden 3" (2012).
