Personally I think eurocenters logic is wrong. Lets be honest most if not all famous mmorpgs have a trade system and seem to be well off. No offense, but there are other ways of making money rather than completely removing the thought of a trade system. First of all, they don't have to sell guns in shops. Second of all they can make it harder to find materials or guns. By doing this players will be forced to earn gralats to buy certain things from players. To do this they would have to set prices to certain objects or items based on the economy. Third of all, more gralats in economy makes everything inflate as not everyone can have the item. Even though they will most likely dismiss this post as well as the thousands of others of trading posts. I personally see nothing wrong. And if they want they could make exclusive packages or what not that you can only obtain through buying them. They don't have to make everything tradeable. I think it's more of a let down to players as some people love the merchanting aspects of mmorpgs.
