Easy. Not many levels.
The game is fun. Especially when you catch a big fish for an even bigger fight.
Playing this is only worthwhile if you have the rod controller or a regular gamepad with a rumble pack.
After breaking several records like catching a 187 Kilo Marlin it gets old... but if the fishing urge ever strikes back I go back to Marine fishing over the Bass.
I don't suggest buying this if you look for long term play. But certaining rent it, or buy it for cheap.
Happy fishing! <><
