Sorry for the digging this up. I was fishing today and was kinda annoyed with it. I won't bother whining about the lemming so here are what I think that could spice up fishing a little bit.
Give us some clue of what is on the hook. This can be related to skill proficiency, H&G comes to mind. Then colour and percentage indicators on options you choose in the process. To make this interesting and less arcady, the success chance on using an option depends also on proficiency, L&L, perhaps or H&G for simplicity . And lastly, a meter where people can see how near they get to land the fish. Hope this doesn't piss off you hardcore fishermen out there. Ciao.
