well. it comes in three editions. one being more expensive then the other. But they probably went down in price now. The regular edition may cost $49.99-$59.99 in some places. but you could get it for $39.99 used. The limited edition and legendary edition (if there are any more in stock) may cost $69.99 and $149.99 respectively. However, i did see some legendary editions go for $89.99 at Wal-Mart.
i'd advise that you just search around and see for yourself.
