I use cash for pretty much everything I get, I rarely shop online unless it's for something really rare and hard to find. For example, I won a tlk tshirt on ebay just a few weeks ago, it was just good for me that the seller accepted other ways of payment, so many people limit it to credit cards and/or paypal anymore.

As for the game, thats understandable, although there may be other ways to keep people from making multiple accounts too. Perhaps they'll figure something to make it more open out so that everyone can play it.
