Spin fishing from the bank needs some spice, to be honest the game itself needs something new but that's a different topic for different time.
What if we could buy "lure cams" witch would grant us access to similar screen like float screen, except in that screen we would see our lure underwater. It would be exciting to see the fish strikes, similarly as you can see pikes strike top water, for me its one of the best feeling in the entire game when you see 15kg pike's head devour a jerk. What if we could similarly see more of the species!
I will never buy a house for 100k, I'd buy a lure cam for 50k though.
