It is not so bad when it is considered more of a leisure time activity, and not simply 'just a game'. It isn't like CLUE or MONOPOLY after all. I live in Colorado where lots of folks have leisure activities that are much more costly - climbing, skiing, etc. with respect to equipment necessary, travel, lodging, lift-tickets, or other costs associated with the various activities. In the scheme of things, even if I spent the cash for a new book every single month, the amount pales in comparison. Even 2 or three books would not match up to a trip to Aspen or even one of the second or third rate ski slopes. Go to any sporting goods store and browse through the hunting or even just the camping/hiking sections... you can spend loads to gear up properly.
Anyhow, the whole gaming thing seems rather cheap to me overall.
