So, I've decided to not look into this at all, but my understanding is that you're scored by like, size and weight of the best fish or added up fish total by the end of some fishing time limit. So like...isn't this mostly up to the fish? This meta feels VERY rng driven and hardly suitable to competitive play. 
, but it came to kind and I'm curious how the fuck anyone gets credit here. If anything it should be whoever can catch any fish first.
They had Krakens and Leviathans and Cthulhus way back. Fisherman were zany. Imagine reeling in Poseidon.
"oh hey Poseidon, sorry about that. Actually before I catch and release ya, a little birdie told me Laomedon wasn't planning on skipping out on your fee for that little construction job you did.
