"Useable"
yes please, i was thinking about this.
I’ve played a game that had a really detailed trading post. You had options for better weapon than currently equipped. Better Armor than currently equipped. There where tons of other options like that too. I think you could even search for items better than your current equipment, but that was affordable or within a certain price range.
So yeah the Trading Post in it’s current form really is a bare bones version. There’s room for tons of improvement.
