GameXplain Says: "But what if you’re a gamer who wants to do more than play those games? What if you want to collect the classics the same way motorists collect classic cars? Unfortunately, it’s almost impossible to tell which game is going to be a rare find in the future. Sometimes it is dependent on the amount of copies printed, other times it’s on how revered the game is, still other times the entire console and by extension all the games on it are a rarity. The caveat to this is how much would it cost you?"
