As the title might suggest, the fleeting nature of time is an important aspect of gameplay in Ephemeral Fantasia, Konamis first role-playing release for the PS2 console. The game was released in Japan under the main title Reiselied, which is a German word for traveling song, with Ephemeral Fantasia as the subtitle. In either version, the player takes on the role of a young bard named Mouse and the adventure takes place in real time.
