As it is right now i dont think you will be able to make alot of gold.I enjoyed fishing in MO1 and found it profitable too in fishing rodspine and other fish. I find the mechanics in MO2 more reaslistic which adds to the experience but I'm far from making a profit on my efforts. I may soon but its been a slow process and quite costly. I'll persist but may change in time as I find it's just not making enough gold per hour.
You will make it,sure but you could have had double or triple the gold per the time invested killing other stuff in the world
