Are your retro games still worth money?

That old pile of games could fetch some cash, but it depends on how rare the games are and the shape they're in.

German Suarez/Shutterstock If you've got a large collection of video games sitting in the back of your closet, you might be wondering if it's an untapped goldmine. Though the chances of having a game that could pay off your mortgage sitting and collecting dust are slim, there's potential profit to be made from many retro titles. However, it can be tricky to know what's worth something, and where you should sell anything that has value.

Outside of a few examples famous for their rarity and worth, like Tetris for the Sega Mega Drive, where fewer than 10 copies are known to exist, there's no definitive list to precisely explain what your collection is worth without more information. Several different factors will determine how much your old video games could go for today. With a bit of studying, you'll know what can fetch some cash and what should be dropped off at the thrift store.

Which console the game is for can have an impact on its overall rarity, too. GameCube games are particularly expensive , for example, and tend to fetch a higher price than PlayStation 2 titles despite being from the same era. This is because the GameCube itself sold fewer units than the PlayStation 2 by a significant margin, so its games also tended to receive fewer prints. Titles that are special editions, regional variants or from other obscure sources are also likely to be worth more. An extreme example is something like Nintendo World Championship Gold for the NES, a prize doled out by Nintendo Power magazine to just 26 winners, which easily fetches over $100,000 today.

However, even the rarest items are impacted in value by their overall condition. Games that are CIB (short for "complete in box," meaning all auxiliary items like manuals are present alongside the packaging itself) are worth much more than loose games, and even more so if they're still sealed. There are other clear visual cues that help determine baseline value: if a disc is scratched or cartridge art is highly degraded, it's not worth as much.

The good ol' nostalgia factor is always at play with video games. If you own titles that are part of a beloved franchise, like Pokémon or The Legend of Zelda, chances are you'll have more baseline value to work with. Even games that were massively printed, like Pokémon Red , Green , and Blue, which sold over 31 million copies worldwide, can still fetch a pretty penny.

A game that's received remakes or re-releases over the years can see a drop in value, since nostalgic players have another option to fill the void. Your copy of Zelda: Ocarina of Time , which already generally sells for less than its price at launch, will likely take even more of a dip thanks to the Ocarina remake . However, this isn't always true — the original Silent Hill 2 , for example, still sells for a significant amount despite its remake, so it's always best to check market prices.

It's well-known that when you take your games to somewhere like GameStop to sell them, you'll make less than you would selling them yourself.
