If two twins have a profile each can Kinect tell them apart? I don't have a twin or anything I'm just curious.

Probably not, unless one of them is fat and the other skinny.

I would guess It might be able to if there is at least some sort of distinguishable difference like height or something. Otherwise No, it would probably ask you to confirm your profile manually.

Confirmed. Kinect hates twins and people with darker skin. Damn you, Microsoft.

my twin brother fooled kinect into thinking it was me and screwed all my savegames

Ya, know I would've never even thought of that.  I wonder if Microsoft did?

...so wait, Kinect is racist AND Twinist?  
 
What's next?  It's pro-liberal and for the gay agenda?

I have twin sisters, unfortunely I don't plan to buy kinect anytime soon so i can't confirm it.

Does this even matter?

I say No because the way Kinect works. It relies on many infrared lights in order to get a general idea of the movement you're making. That's why there a minimum distance because it Kinect literally has a blind spot. Kinect is basically a fancy infrared detector no different then the infrared detectors security companies use.
