In the end, Echoes of Time is one major step forward and several steps of varying size backward. Ring of Fates emulated the multiplayer aspect of Crystal Chronicles superbly to make an outstanding single-player experience. Echoes of Time instead hearkens back to the series roots by making a game that is an interesting experiment that could have shined with a bit more work. They got the multiplayer right, but the solo play is as bad as it was in the original game.
Also, the idea of a DS/Wii dual launch sounds great on paper, but the interface of the Wii version completely ruins the effect so badly that it feels like it was tacked on at the last minute. There are a lot of good ideas in this game, but the poor execution mars what could have been a breath of fresh air.
