Humm, you will agree with me that the above comment from cartandweed is a spam, ain’t it? There’re no button to report it though…
Well, to bounce back on the subject, I’d love to see more trade as well but as you quoted, this is definitely not a trader brother game.
Yet, there are some brothers that are good merchants, aren’t they? They lack battle skill but they allow you to buy or sell products with profit or at good price… The problem with Battle Bother is that we never keep track of previous cities prices and we can’t see what are the products sold in the city unless you visit it.
Seriously, if you are really into trading games, I’d advice you to take a close look at games like “Merchant of the Skies” or “Merchants of Kaidan“
