Most reviewers rank Dragon Quest Swords: The Masked Queen and the Tower of Mirrors
as mediocre, but $17 sounds like a fair price for the game. If you happen to agree (and can buy games from Amazon.com), you should probably hit up Amazon's "Deal of the Day."
The battle system might take you to "Waggle City" and the story might fall a little flat, but cheap prices tend to make up for these things. Then again, the price of Dragon Quest Swords
has been dropping steadily at Amazon for a while now, and might even go lower
in the near future. Unfortunately, we're too busy to get into our time machines and check.
