The Xbox LIVE 'Countdown to 2013' daily deal is all kinds of kid-friendly today; though, these kid-friendly games are great for adults too! I never expected Toy Story 3 to be anything other than some cheap tie-in game, but it surprised me with how much fun it was and the 'Toy Box' mode is just fantastic. I hate the Cars movies and didn't care for the first game, but Cars 2 (the game) is actually pretty good because it's basically Blur with the Cars license--Blur is an awesome game you should hunt down for super cheap.
Anyway, you can find the linkage and all that jazz below. And I must throw out a special shout-out for Banjo Kazooie: Nut & Bolts; if you've never played it, it's a great game that far too few played. It may be a deviation from the series, but sometimes deviations are a good thing.
Banjo Kazooie: Nuts & Bolts [GoD] - ($14.99 ---> $9.99)
Toy Story 3 [GoD] - ($19.99 ---> $9.99)
