Look, it's mahjong. This isn't the next big thing. It's a fun, casual game that will fill in the gaps between your action games and hardcore role-playing games in your PSP library. It's a great road trip game, with its 100 game boards and various game modes. I can wholeheartedly say that it's worth the $3.99 asking price...if you like mahjong.
