sometimes i can't find things i need at the shop this would be helpful

I don't think this would work due to the lack of players, if 1000 people played the game maybe but if there is 100 players this won't solve your problem.

true but maybe when the game is opened possibly?

It could be a good idea, but I'm sure items that would be hard to get would be expensive and hard to get in an auction as well.

You might experience the same problems.

yes it would take a lot of work
