One of these retro games was sold for over £1,700 on eBay

Financing a full price video game these days pretty much forces you to consider selling your dog, but what would you say if we told you your retro collection could be worth a small fortune?

Even if a lot of them look like utter sh*t in the age of 1080p and require you to untangle a seemingly never-ending reel of cables just to boot up a machine to play them on, games from the 80s and 90s can give you a sizeable payout if they're in decent nick. Thanks to Mr Gamez, we're able to see exactly how much some iconic titles have fetched on eBay. The price is dependent on their condition, but some of the values are pretty staggering. Have a look at these, and prepare for some double-takes.
