The Mega Pack includes a PS4 with LittleBigPlanet 3, two controllers, PS camera, and an Oddsock plushie. It's a damn good deal if, and this is a fairly big if, you're going to get good mileage out of the hardware involved. If you're planning on spending lots of time playing around with the camera in LBP 3 or will be building on your game collection with further titles offering local multiplayer, then this is a pretty good shout.
Oddsock sort of looks like he's been messily eating cake, though. Or liquorice. Cheers sunking!
