This weekend, Sega announced that it would bring its Sega Ages line of classic games to Nintendo Switch this summer, starting with Sonic the Hedgehog, Phantasy Star and Thunder Force 4.

Today, Sega confirmed that the Sega Ages games are bound for North America and Europe in addition to Japan, and revealed two more classic games: Alex Kidd in Miracle World for Sega Master System and the original arcade version of Gain Ground. That means that Sega plans to do more than just re-release classic console games as part of the line, but arcade games as well.
