This isn't a title that will win you over. I think if they hadn't cartooned it and tried to hit the older gamer they would of had a better title. Kids don't care about fishing and especially hate reeling in cat food cans every other cast. Now, I enjoyed the title, but my kids quickly, very quickly, handed the controls to me. This didn't hit the mark, but you will enjoy it if you like fishing in Japan.
I don't like fishing in real life. I find it very boring. Well several years ago I was in an store and saw Sega Bass Fishing for the Dreamcast for 9.99. I bought it and was hooked (excuse the pun). I even bought the fishing controller which made it jump to the next level. Ever since the Dreamcast days I have been hunting for a replacement and with the Wii I have hoped even more. Well I am still waiting.
Don't get me wrong this isn't a bad game but it's not one that I wanted to play nonstop. In fact after about a day I got bored, it just seemed to be the same thing over and over. I really felt no pull to get new fish nor did the locations do anything for me. In fact the locations were just plain ugly.
My suggestion is to rent it if you want a fishing game to play for the weekend.
