Further to the thoughts of fishing and fishing equipment, I would quite like
to see a bit of an expansion of what merchants get up to in general.
Also, as I already mentioned somewhere, this might enable merchanting to be
broken up into various sub-guilds which could be multi-background.
Fishing with nets, farming, large scale minining operations etc. could all
be carried out in a similar way to shipbuilding.
This could include various types of shops, transportation (including ferry
routes etc).
I guess all such things would take quite a bit of development and are
hardly a priority.
Really I'm only replying to the fishing thread because I want to be
able to fish for kippers.
