Square Enix will release Final Fantasy Crystal Chronicles: Echoes of Time for Wii and DS here on 27th March. That's the same week, and just a few days later, than the US.
The headline attraction of Echoes of Time is cross-platform Wii and DS multiplayer, which lets up to four people adventure together regardless of platform or geographical location, within reason.
To achieve all this, Square Enix appears to have stretched the DS game onto Wii rather than develop two very separate games.
Otherwise, Echoes of Time tells another story of another boy-hero venturing out into the world to make an RPG name for himself.
