This was an unconventional move by the Wiiviewer, as he has reinforced over and over that he doesn't want to review any Zelda games. He has actually kept to this promise pretty well, having only reviewed this game and The Legend of Zelda: Skyward Sword for the Wii. However, he reviewed the game out of being in the mood to play, and simply deciding to review it out of interest.
The Lilwiiviewer showed a pretty good deal of resentment toward the game, as he believed that the game was "too hard," with too many enemies and not nearly enough clarity regarding where to go next. However, in the end, he didn't necessarily believe that the game was worth either a "Buy" or a "Skip," but rather made the outright statement that it wasn't his type of game, and essentially that given the time period, he wasn't the best person to ask for an opinion. As such, he deferred to the Wiiviewer who, despite admitting that the game will kill you constantly, and that it is hard, you will return to it over and over for the sheer fun of it, and to make your way to the end. Therefore, he declared this game to be a "Buy."
