In dollars, Skylanders Giants is still the No. 1 selling console and handheld game in the US and Europe - including its toys and accessories, Activision reports.

Activision notes that Giants sold more than 500,000 Starter Packs globally in its first two weeks last year, and the Skylanders franchise has generated more than $1.5 billion worldwide in its lifetime. Activision expects Skylanders figures to outsell the top action figures in the US and Europe during the first eight months of 2013. A new competitor to Skylanders, Disney Infinity, sold 294,000 units in its first two weeks in the US alone and was ranked No. 3 in overall sales for August, according to the NPD.

Skylanders Swap Force, the third full Skylanders game, launches in October for Wii, Wii U, Xbox 360, PS3 and 3DS, and later this year for Xbox One and PS4.

Update: Activision's two-week sales number of 500,000 refers to global sales, while Disney Infinty's numbers cover the US only. Activision notes Skylanders Giants "remains the biggest kids' videogame launch in the last 12 months in the US and Europe," based on revenue and according in part to Activision internal estimates.
