In World Tour mode, you take a user-created team through a tournament, earning points as you go that allow you to increase the stats of your players and also unlock special teams and players, including one based on the character Ulala from Sega's Space Channel 5 series.
The Dreamcast version of Ephemeral Fantasia was to feature cameos by Sega characters including Sonic the Hedgehog, Ulala, Ryo Hazuki, and, oddly enough, notable Sega developers Yu Suzuki and Yuji Naka.
