Little deviants is very much a set of games within a game. There is no real story line and instead is alot of very well designed mini games. The comic and "bouncy" style of the game adds to the enjoyability of the game and most importantly it is very easy to pick up and play anywhere. Games like uncharted are great however your terrified of missing any of the story or action, little deviants however does not have you worried about any of these things and is great fun with the sound either on or off.
The mini games make use of all of the vitas functions and as such is a great first game. All but one of the mini games can be played anywhere however this one mini game required you to rotate on the spot in order to shoot down planes, you may get a few strange looks if you do this on the train.
