The first title on this series alongside with Love & Berry, were one of the reason that allowed Sega to rescue the AM market in Japan. Both games were made huge success making Sega the pioneer and leader of kids arcade games using trading cards.
However, Sega has lost this position for the others makers like Takara Tomy and Square-Enix, and now are doing a lot of efforts to recover the first place.
Sega is using the know-how of Shogakukan, another company popular with the kids, but is not doing effect. At least, they are not successfull like when Sega did all alone.
Too bad...
Curiously, Golden Axe original music composer still working at Sega, doing musics for these kids games ;p
