In stark contrast to the Cheapest Games series, this Rare & Valuable series will round up the rarest and most valuable games for a given console or handheld so you'll know what to look for whether you are buying or selling. Below you will see two prices beside each title. The first is the average daily selling price, which is typically the going rate for the game by itself. The second price is the highest price in the past three months which is usually the price for the new/sealed game. Note that some of these games are not rare in the sense that there are not many available, but rare relative to demand, which makes the games expensive.
