Man, the 3DS has so many skills. We've already talked about a lot of them tonight, like the Mii-from-a-photo skills, the fight-strangers-in-Street-Fighter-without-knowing-that-you're-doing-it skills, and the ever popular portable-virtual-console skills.
That's a ton of skills, but this may just be the start of the 3DS's powers. From the looks of this video, the console also allows you to fight real life monsters that appear out of "? block" playing cards, as viewed through the 3DS's camera. It's like the 3DS is actually a pair of glasses from They Live, and the aliens have invading via card form. It's pretty much the strangest feature I've seen in a gaming system to date.
There is a lot of other weirdness in this video, but I don't want to give it all away. Watch for yourself and tell me what you think. I'm particularly interested in hearing your thoughts on the catchy music, and the way that everybody's dressed.
