LittleBigPlanet was a masterpiece. Had it just been a platformer, we'd have criticised it as being a floaty and imprecise, but its campaign was just a tutorial for a massively powerful editing suite that let you create your own content, levels and even entire games. Play Create Share was the name and LittleBigPlanet was the game that started it all.
It's the Essentials Edition, so you'll get the new box sleeve, but the game itself is still a fascinating way to express your creativity and design some utterly bizarre things. Before deleting it all and downloading levels from players who actually know what they're doing! Another great spot from FantasyDeals.
