do it LoZ TP style
In an MMO, that kind of interactivity would be hard to manage. It's also a little long per fish for this kind of game. People would be angry over how much easier it is to do other skills as opposed to chasing fish down with a lure.
avoid runescape's fishing skill completely
Sadly enough, runescape had a good tier system where the progression is good (Bigger, better with higher level) and with a moving fishing spot, you had to keep interacting with multiple steps, such as:
1. Where did the fishing spot go?
2. Is it the same type of fish that I am aiming for?
3. How many other people are using the spot? (More people cause a spot to move faster)
It sucked, but it had more to it than say... FFXIV does.
Literally have fish swimming around and you have to move the line around to get them. Bigger bait will attract more and if you throw the line in the water hard enough it'll scare the fish. Also, movement is meant to be little and etc.
With a massive amount of people, having literal fish swimming around can't be done easily. Either it causes a lack of fish (where only one guy gets "the" fish in the water) or it causes annoyingly long wait times where everyone is just throwing fishing lines in the water hoping to get one of the fish while other games feel more rewarding with their old systems.
make a ton of fish species and the higher your skill the more better fish appear with magical properties like regenerating health
as for the actual minigame idk
The point was to come up with ideas for engaging gameplay.
denpa men has a cool thing in which when you snag a fish a bar pops up and basically what happens is in a way you fight the fish until its health is depleted, being careful not to make the line snap
Never played that game, but this is a good idea. It's simple and engaging. It also helps with needing fishing tools, seeing as your line can snap, and a higher level fishing pole would last longer, etc.
Thanks.
