I'd like to see fishing in the Skyway. For those who don't know: if you tap the "Tab" button on your keyboard while sailing, you'll go from sailing to walking around on your ship! So, maybe use this feature while fishing... AND picture this: Since you can have multiple people on your ship at once, you could have a fishing party. I'd like to see a way to sponsor a fish-off on your ship, everyone would pay to join, and whoever wins gets to take home the money... and maybe add a betting system: so if you lost, but you bet on the winner, you'd still get a small reward?
I just realized how similar everyone's ideas were. pretty much ALL of them took place in the skyway... which seems fit, maybe we could sell them to people on the docks... obviously Jonah Town would buy them.
