The game does a good job of modelling underwater environments in 3D. The adrenaline rush of seeing a giant gamefish emerge from the murky waters is palpable, and it's quite exciting to see a menacing shark coming out of the blue, looking for blood. As far as I can tell, game physics is reasonably realistic. For example, you have to always watch your oxygen level while underwater, and deal with the perennial balance between weight and usability while you choose equipment. Dangerous predators make the game more challenging, and you can toggle the difficulty level if you find the game too hard or too easy (there are 3 skill levels in total). Dozens of equipment, 14 species of gamefish, and solid gameplay makes this one of the more interesting fishing games on the market. It is repetitive in places, but it should not deter fans of the sport who take the adage "patience is a virtue" to heart. Recommended!
