Highly underrated. This is a good sim, don't believe the negative reviews. This review from someone ACTUALLY who owns it

User Rating: 7.8 | Rapala Tournament Fishing! WII
Graphics: 8/10
First off, the Wii was NOT built for graphics, it was built for fun. - If the Wii was built for graphics it would have a much more powerful processor and GPU. Anyways, why do you need ridiculously good graphics on a fishing game? Sure, there are some glitches in the graphics that should have been improved which is the reason why I gave it a 8. Personally, I would never expect (even on a future-gen console) amazing graphics on something like a fishing game.

There are a few sensitivity problems in this game. Sometimes when casting, the Wiimote does not register the cast and you have to recast. Also (rarely) does not respond to jiggles, pulls and tugs when reeling in a fish. But a simple flick of the wrist to recast is no big deal.

Use of the Wiimote: 9/10 [Averaged with Interactivity for Gameplay rating]
Perfect implementation. Would have loved Nunchuk reeling, but, you cant have everything.

Sound: 6/10
No music (although with this kind of game, thats somewhat of a good thing) except in opening credits, definitely a negative. They should have done what Nintendo did on Excite Truck allowing you to listen to your own music from an SD card. The other sound effects are fine.

Difficulty: 5/10 [Averaged with Interactivity for Gameplay rating]
WAY to easy to master reeling in fishing. After playing for around an hour or two, you can pretty much catch anything that tugs your line.

Tilt/Re-playability: 6/10 [Averaged with Interactivity for Gameplay rating]
Ok, this isn't something you can play for hours and still be entertained.

Controls/Responsiveness: 6/10 [Averaged with Interactivity for Gameplay rating]
Definitely dont agree with using D-Pad Up to power the motors and go in reverse. Should have used A or B for this. Also, the "code to land" should have been better implemented. It registers your land as "Failure" if your holding any buttons when it pops up.

Remember: Gaming shouldnt be measured on graphics or sound. You could have a game with horrible graphics and still be fun.
