Denzio has a great idea but I never got a mounted fish doin any of the fishing (gold hunt has fishing just click the huds arrow and it changes to fishing hud all in one)
some give you items like 7Seas and all the farm systems fishing but again like many who read this IDK what you consider a grid wide game. any rp system that has farming might do as all the farm systems now have fishing but one.
so look up Arora, G&S, and DFS (newest and most contemporary looking) I never got to play WW but I will post links over the week to help you decide if its what your looking for.
but they is not a fighting games the first do allow for fighting and weapons to be made but I am not an expert.--Please search my posts I will post more about all these-
