This game deserves much more attention. Most people will like the game even if they don't like fishing! Worth your $40!
+ve:
You explore the whole Japan with new fishing spots being added. You step up from fishing beginner to fishing master (there are many rank titles). The fishes are fun to catch. Every kinds of fishes have different responses when you hooked them. Some are easier, some are very tough and tricky. The variety of fishes are what makes the game so addictive.
There are different challenges from your grandpa and tournaments in different states of japan adding more depth to the game. There are a lot of hints and funny messages posted on the bulletin boards within the shops. There are even descriptions of every fish and ways to cook and eat them. -ve:
Graphics are cute and decent, but the sceneries are just ok.
There's not a compelling storyline going on other than conquering the whole Japan with fishing skills.
Anyway, don't miss this game! You can even play the game with or without nunchuck, reeling with your nunchuck, or press downward with joystick/d-pad. So you don't need 4 nunchucks for 4-player mode.
