interesting...(being a parent)...

would they have a problem with buying you a basketball? Or a deck/booster of Magic: The Gathering cards? Or a console game?

...just pure curiosity

edit-
Also...@mikey (kinda)
As long as the game is fully "playable" in its free form, I dont really think it's dumb for them to have ppl pay for any add on. It's what keeps their business model going and what keeps the game free

Lol. It's really dumb to pay CS for a game, 'cause you won't play forever and it will always come new games to play or you will get bored. Also it's a graphic item and nothing in-reality.
