Video Game Winners and Losers: November 2013

Every month we write an article with a list of some of the games with the biggest increase and decrease in price. We call the series "Winners & Losers".

Winners: Video Games With Biggest Price Increase

More Winners
Robot Alchemic Drive for PS2
King of Monsters for SNES
ActRaiser 2 for SNES
Nosferatu for SNES
Skyblazer for SNES

Losers: Video Games With Biggest Price Decrease

More Losers
Fatal Frame for Xbox
Asphalt Urban GT 2 for DS
Shin Megami Tensei: Devil Survivor for DS
Cradle of Rome for DS
Super Star Kartz for DS


The list is made up of the games with the biggest change in price compared its average price in the last two years. We use the standard deviation for the prices to eliminate games that naturally have volatile prices.

For example, a game has an average price of $10 and a standard deviation in this price of $1. 96% of the time prices will be within $8 and $12. If during the next three months the price jumps to $14, then $15, and $16 after that we can be very confident the price increase is statistically significant.

Great article! Robinhood surprises me because I consider that a fairly common game and one I don't think many people have warm nostalgic memories of. I had just heard about Sky blazer and was hoping to pick it up at a decent price. I guess I should have found out about it sooner.

@PBR, sad thing about Sky Blazer is that it appears to be continuously climbing too. So it's not like you can wait until March and get a better price.
