Super Rub-A-Dub is a highly enjoyable game, although controls could have been better, this doesnt affect gameplay at all
As for the gamespot score, i'd disregard it and focus more on the 'user score' as it's much more accurate.
The Game:
You control a rubber duck around various mazed bathtubs and collect little baby rubber ducks, in many of the levels you must avoid sharks (even GIANT sharks) to avoid getting the baby ducks eaten (or popped).
The gameplay is simple and the sixaxis works well (even though it could move a little more fluid) with the game.
This game is well worth the cost and is very enjoyable when you have friends around as it can be played by 4 players (with one controller)
