Quoted from jgentry:He needs to pay for any items you bought for the game within reason. Maybe purchase them from you?
If you buy items for a game not yet in your gaming area you're taking a risk.
Learn to manage your own risks. You wouldn't have the seller keep your payment if he called and said the game was struck by lightning and burnt to the ground would you? Of course not.
Write a contract if you want to minimize things like this.
