Sega may not release Phantasy Star: Complete Collection outside of Japan, but importers should have no problem enjoying it. In addition to including Phantasy Star I-IV in Japanese, Sega is inserting the English ROMs too. This means you can enjoy enhancements like easy difficulty and faster walking speed in classic Phantasy Star in a familiar language.
All right! Oh, but Sega doesn’t have a translation for the eight Phantasy Star II text adventures. I still can’t complain, this is way better than nothing and special thanks to Savory for pointing this out in the comments.
