Do you mean you couldn't figure out how to fish, or it was just too tedious and therefore "didn't work"? If it's the former, I struggled at first too. I'd click the button as soon as I heard and felt the bite, but it always failed. I realized after a while that you don't click the bite until the bite actually pulls the bobber under the water and bends the rod, THEN click the button to start fishing. Sometimes it takes 4-6 "bites" before the actual animation you should click for. Once you hook a fish, the mini game of keeping the fishing lure within the highlighted area is clunky for me, and I'm not great at it. I probably just need to practice. I really haven't bothered to fish more than maybe 10 minutes other than when it's required for a quest step in act 1.
This was me, I only tried it for the first time standing on the edge of the ocean getting buffeted by the waves in pursuit of the "very special" whatever for the quest. It took about 10 min to get the hang of it for me, but then it was pretty easy.
What an amazing game. Act 1 was just so good. While it wasn't perfect, other than one or two off notes (If you chose picked one faction, the speech at the end of Act One was, ehum, a little too modern for my taste, and the overall themes a bit too Current Day™, its pretty easily overlooked given how well the characters are written ( with a couple of notable tin-eared exceptions that aren't in the game for long). Are they good guys or are they bad guys? Its pretty clear Devs want you to lean a certain way with the Iconography/narrative but there are things that would let one justify going the other way in a playthrough.
It's really is amazingly fun: Melee/stealth/ranged/Magic can all be overpowered if you build it right; [At least in Act 1, I don't know how well that holds up] Day and night have distinct gameplay, with night more difficult, its just so well done. Even if Act 2 on were unplayable I would have gotten my money/time's worth out of the game. I finished up every single quest but the Stagfather's shrines and hit Act 2 at level 30. It is amazingly fun to blow Outlaws off towers with Scorchers Blaze or whatever. My one overarching complaint is it is nearly impossible to find a corpse if you aren't bird-dogging where it goes down. If it flies off, falls off a structure, in tall grass, or at night? Forget about it, Dave, it may as well have fallen through the world. Which I think they sometimes do; when running through an area I will see skeletal remains in combat areas that appear to be from previous fights, re-surfaced from the Great Below.
Overall I can't say enough good stuff about this, Morrowind/Oblivion with a soupçon of Elden Ring/DS. You have levels but the mobs don't but the game rolls them out to you pretty well in a tiered fashion. If you just ran to the North/west of the Map right of the gun there would be some smoke-age I would assume.
