An excerpt from Destructoid's review:

With Fortune Street, all the fundamentals are there, but the devils pop up in the details. For starters, it takes forever to play through your average game. The game itself moves along fairly quickly, without too many lengthy animations to sit through, but there is just so much to the game and it's so hard to win (or lose) that it just goes on and on and on. I've played a match online that lasted five hours (though my average match has been closer to two to three hours long). That would be okay if you could save and quit, but expecting anyone to spend half a work day playing a board game simulator is asking a lot.

There is also the fact that, in order to unlock all the game's boards, you have to play through the exceptionally long and repetitive campaign mode. This goes for a lot of the Mario-based content, too. Many of the boards and their accompanying musical themes available from the start of multiplayer mode are based on the Dragon Quest universe, and as such, lack the pep and punch necessary to keep you from falling asleep during one of those two to three hours games. I had a hard time keeping my friends playing past the third round on the first board we played on, which featured some slow baroque jams and a relatively lifeless castle in the background.
