25 Highly Valuable Games You Might Actually Own

16. World Of Warcraft Collector's Edition

Platform: PC Released: 2004 Potential Sealed Price: $2,600 Potential Used/Worn Price: $300

The World of Warcraft Collector's Edition mostly owes its value to the extremely rare in-game 'pets' that come with the key. The much sought-after digital critters can go for up to $1800 on their own, just for the code that lets players unlock them.

Even if you own this collector's edition and have already activated the game key, the box itself (with the goodies within) can still go for up to $300.

15. Shining Force III

Platform: Sega Saturn Released: 1998 Potential Sealed Price: $2,499 Potential Used/Worn Price: $250

Shining Force III was a relatively unremarkable entry in the Sega's fairly solid RPG series, other than its use of the 'scenario' system. The game was released in three different parts in the Japanese version, with only the first seeing release in North America.

In mint condition, Shining Force III has been sold on eBay for $2,499, while more battered copies can go for anywhere from $10 to $250.
