Superstar Saga was a borderline masterpiece, but after all these years and all the Mario & Luigi games I'm convinced it was a total fluke, and Partners in Time was the first sign of this. To put it bluntly, this game was a huge let down, but it's not completely awful. The excellent combat from Superstar Saga is still here, and a couple of the worlds are engaging enough, but that can't disguise the overall blandness of this game.
