Just getting into this. I like the thought of chilling and doing a spot of fishing in RDR2, but in FC5 it's too easy. Cast, catch fish, reel in. There should be an element of waiting, suspense, like "oh my god I hooked a fish!" instead of it being 3 seconds after you cast in. I wouldn't mind sitting for five or ten minutes next to a fire, waiting for something to take the bait.
As a side note, I found a way of making super quick money in FC5 just from shooting buffalo and cougars, then fast travelling. Like 4k every 5 minutes.
