Just in case you didn’t max out all your credit cards on Black Friday, online retailers have fabricated a new bastion of American consumerism in recent years: “Cyber Monday.” It’s the Monday after Thanksgiving, and while Black Friday is still thought of as a day for brick-and-mortar retailers to make bank, Cyber Monday was designed to help so-called e-tailers kick off their holiday shopping season. It’s even got its own Web site, CyberMonday.com, which is sponsored by the National Retail Federation’s Shop.org -- so you know it’s legit!

So why should you give a damn? Why, because there are some great deals to be had on videogames, of course! LittleBigPlanet can be found at Amazon for $39.95 (20% off), Best Buy is offering a free 3-month Xbox Live Gold card with the purchase of Gears of War 2, and you can get Ninjatown for half price ($14.99) at GameStop.com. Follow me to the jump for the best of what Cyber Monday has to offer videogame-wise!

[Editor’s note: Most of these deals -- especially the ones at Amazon -- are only valid while supplies last; if you happen to click onto a particular item’s page and you see the regular price, then you’ve missed out. It’s already Monday all across the continental US, so go, go, go! Also, you can click on the images for all the retailers except for Target to be taken to their respective Cyber Monday videogame deals pages. --Samit]
