One of my favorite things to do in XIV is to sell things. I like buying and reselling and trading. So why not have large shops, except where players can run them?
It would be a PLUS to the retainer system
Now this would be an extension of the retainer system. Players would need to purchase or buy a plot of land and would be able to sell more than 10 items at a time. It would be a sort of entrepreneur class.
How would it work?
Players would have to sell, buy things at FF-specified minimums, sort of like NPCs so that it wouldn't hurt the economy, but would actually help set more solid rates on items.
Other types of shops
You could do it where you could have 2 or more types of shops, you could have a shopping strip where it'd be easier to get a stand, like rented stands in the market wards, (these would cost more, and would be rented), and then there'd be major shops within the city.
Other small shops would be the "traveling peddler class" where players can set up a small shop of wares (on the back of chocobo maybe?) and set up near crystals and other places of meeting.
What about keeping it stocked?
Players would be able to get their wares wholesale from a large system and they could choose to have a bazaar shop, armour, weapons, materials or more based on the type of lease they have.
Lastly, players could also assign a clearance bin where customers could bid on items and even give things away. This would be good for items that players need to move or items they had on them theirself etc.
Why do we need this?
Having something like this would set a better economic standard on items, it would be very fun, it would give better deals than NPCs do, and it would be more player-driven. I would like this far more than crafting. It's almost the same type of thing if you think about it.
Discuss. If you'd like to see this, comment, or share any other ideas that would make this fun.
