 Due to the game's last-minute recall and subsequent delay, "LittleBigPlanet" was released mid-week and as a result, its first week performance indicators are based on four days instead of the usual seven.This has also been suggested as a contributing factor.Many supporters of the game have suggested that a lack of advertising has let it down although advertising campaigns were launched in North America and Europe which helped to boost the game's sales in the run up to Christmas.
