I bought some PS3 Playstation Move Game called TV Superstars from Best Buy for $1.99. Brand new too. I'm guessing it wasn't selling well.

I managed to snag Bloodborne for 5 Dollars.

Star wars rogue squadron 2 for $2 at GameStop and a new copy of max Payne for $1.50 at best buy

I think the cheapest game I bought was Magic Carpet used on the PS1 for about 2 dollars. I loved that game, and for that price I couldn't say no.

Dont really know, i bought many games for ~4€ online or in various stores, used of course.

When it comes to new/sealed: In 2014 a major retailer called Saturn they still had Lumines brand new for PS2 lying around, i got it for 5€ before they completely got rid of their PS2 stuff in bargain bins.

Legally?Around 7 euros for Metal Gear Revengence.Now illegaly, around 4 dollars for a pirated PS2 game.

I don't remember. I got Gravity Rush Remastered for $9 when it came out though.

1 pound for Fifa 2010

Brand new the cheapest game I ever bought was NBA Street on the GC for $2.54, which is what it rang up for at the register at target (list price at the time was $19.99).

The cheapest used games I ever got were some NES games at my local Cash Converters for $0.99 each. Stuff like MLB Baseball and Ice Hockey, and most other common games.

You used to be able to get even PS1 / N64 games there for dirt cheap like $2-$5 each, but nowadays the value of classic games has increased, especially with the rise of eBay and online price appraisal sites that instantly show the demand for any game and what its current going price is. For example I bought a brand new, sealed copy of Worms Armageddon on N64 back in 2002 during the GC/PS2 era for $20, and nowadays the game LOOSE goes for over $200 regularly, and complete in box (which I have) can go for as high as $500.

I've bought older games for $0.50 before.
