DS Daily: How many games do you buy a year?

We probably don't have to tell you guys that a gaming hobby can get a little expensive at times. Sometimes we look at the lists of upcoming DS titles and idly wonder if we really need two kidneys to get by in life. Unless you're lucky enough to have money to put toward building a mammoth collection, it's likely that there's a limit to your gaming expenses per year. What we want to know is: where do you draw that line? How many games do you buy, on average, in a year? Or, if you're relying on the cashflow of another (for instance: Mom and Dad), then how many games are bought for you? Do you find that you can't always buy everything you want, or do you always make sure you have all the hot new games?
