Okay, this system reminds me of another game, which shall not be named, but is produced by Nexon. (If this post gets deleted then thats bull, because i didn't say what game) Well, anyways, you can buy some extra money using USD, and that is converted to a SET amount, 5 USD = 5k points, 10=10k 30=30k, and that can be used to buy different items that cost anywhere from 800-11k points. But the thing is that their items disappear after a while. Thats what sucks. They also have a "lottery ticket", where you use the ticket at a machine and recieve anywhere from an orange juice to a high level sword.
How's that for an idea? Copy their system, cause there isn't a copyright/patent.
