" If you want to visit another world and trade with its inhabitants, having good products to trade most likely wouldn't be enough because they wouldn't understand what you are trying to achieve. Both the inability to communicate and huge cultural differences would be an enormous barrier. In order to initiate the relationship you need to know how to communicate and speak their language, which may be accomplished through a translator or by learning the language yourself. Learning the language yourself is a lot harder but, ultimately, it's a lot more efficient."
