According to SEGA Ages senior producer Kagasei Shimomura, the overseas reception to the series has been much higher than anticipated. Sonic, Out Run, and Alex Kidd in Miracle World have received an especially big response, particularly in Europe.
Unfortunately, things aren't going quite as well in Japan. Shimomura and supervisor Yosuke Okunari indicated that sales have been a bit slow and they need to appeal to its Japanese fan base. Shimomura added that SEGA Ages on Switch has been selling less than half as well as the 3DS classics that were developed a few years ago.
