Given how they can often result in fence-sitting games that specialise in AAA blandness, gamers are right to be wary of focus testing groups.

I knew that dance games, like Ubisoft's Just Dance series, took an extraordinary amount of motion capture and choreography. But I admit that I never stopped to think about the costumed characters on-screen. Not only does the team have to capture dancers in motion... they need to outfit the dancers, too.

I never realized how dangerous some of these dance moves look to be until Conan took it upon himself to review Just Dance 4 with Olympic gold medalist Alex Morgan.

Here's Ubisoft's Just Dance 4, shown off at Nintendo's press briefing during E3 today.

It's true. Ubisoft's Just Dance 4, out this October for Wii, Xbox Kinect, and PlayStation Move, will feature Carly Rae Jepsen's Call Me Maybe.

Well now we know where one of those 25 million copies of Ubisoft's Just Dance games ended up: In Britney Spears' living room, where the all-singing, all-dancing performance artist recorded her son Preston getting down to a little "Shake Your Groove Thing".

Go ahead, snicker and titter just like you do when you pass a display of Ubisoft's dancing franchise games at Target or Walmart. With 25 million copies sold across six titles, odds are you secretly own a copy of Just Dance yourself.

Somewhere inside the Beltway today, copies of Just Dance 3 for the Wii and The Sims Plus Pets rode in a presidential caravan with the nuclear football. That, gang, is core game cred.

The Just Dance series is the kind of red-hot gaming franchise that can pull in a guest character like Nintendo's Super Mario. But who knew that such a combo would be so... colorful.
