As Tearaway can't be praised enough, here is another anecdote targeted at people who like to play the very best games of this medium.
I have a 7 years old girl, fan of Kirby, Mario but mostly Animal Crossing. She has been playing on Wii and 3DS for a couple of years, I made her test about 20 games. Plus twice as many on iOS.
So I recently got a Vita (sex) and while I didn't let her touch it for a while (sex is for adults)(probably the main reason why Vita is not selling as much as 3DS BTW), I found Tearaway so good I started building Origamis for my girls (I did a Squirrel, an apple and a flower, it's amazing).
So my eldest girl asked me where I got these from, and I showed her Tearaway. End of the story is, she's now 30% in and told me yesterday it's the best game she has ever played.
Buy a Vita you crazy gamers. And get Tearaway, for you, your girlfriend, your kids, and for the sake of this medium.
