IMO the best fishing game would be more of a role playing game and not an action game.
You would be given weather reports, tide info and some basic information from tackle shop owners. Based upon that information you will need to choose a general location to fish, lures to use and if you want to even go out. If you get the right combo of conditions, gear and clothing needed for the conditions the computer will give you how many fish you caught.
You could enter local tackle shop tournaments and get rewarded with better equipment and gear to give you a better chance to catch a bigger fish. At the same time you would build a better relationship with the tackle shop owners and be able to get better intel from thenm.
There will also be a point where your tackle could get stolen or equipment failure because you did not wash off your gear or you did not lock your car up. You will also have lure snapoffs, line breakage so you will need to earn money to replace or repair the equipment and pay for gas.
Eventually you will win a boat which will increase the places to fish but the expenses will increase as well. Maybe the finally will be to win the MV derby or the striper cup.
I would play that game for sure!
