This is not only the most fun fishing game I've owned, and I've owned quite a few, the graphics are incredible not just the realistic looking fish, but the areas themselves are gorgeous and honestly look more like Zelda Skyward Sword in terms of the artistic feel to the environment.
You also Have different types of locations, which ranges from saltwater beaches, ferry fishing, deep sea trolling, ice fishing, boat fishing/shore fishing at 5 different lake and jungle areas, and river fishing! :O
There are about 220 species of fish, tons of bait and tackle, and a huge selection of apparel for your avatar. You can help people doing missions. You can earn items to fish at night or wake up early.
Then you have your very own aquarium which allows you to keep "all" the fish you've caught and view them which the deep sea one looks like a Sea World exhibit.
The game can even be played with up to 3 friends, so yeah this game blows away the competition. ;)
