Well...I already owned the vast majority of my sub books and DVDs before the SH series came along. I only upgrade my computer about every 4 years anyway. This game is far cheaper than some other typical leisure activities venues like attending a movie, going out for dinner or your average ball game nowadays. Plus, there are other game titles I've decided not to purchase due to interest in this one.
Compared to some forms of entertainment, this game is a money-saving bargain.
