LittleBigPlanet Portable (often referred as LittleBigPlanet PSP) is a spin-off title for the PSP developed by SCEE Cambridge. It is a spin-off of the original LittleBigPlanet. It was one of the free titles offered during the Welcome Back package during 17 May to 3 July 2011, after the PlayStation Network was brought down earlier that year.
Before receiving update 2.05, the game was infamous for its level of stability; it would often use all of the PSP's processing power, leading to random crashes that had tend to happen while players created levels and downloaded content. The patch also fixed some minor physics problems.
The plot of the game is very different from the console, but still related. After the events of the first game, the player goes on vacation to many exotic locations. They start in the down under, where they learn about the controls and their immenent journey/mission and make their way to the Carnival of Creators.
In LBP, players control small characters (nicknamed either "Sackboy" or "Sackgirl", owing to their material and appearance), each of which can jump, move, and grab objects. Players can use their abilities to shape and develop the highly manipulatable environment to build custom spaces either individually, collaboratively, and/or competitively. Levels focus on physics-based gameplay, and players can use mechanisms such as cogs and blocks to build anything from small level parts to large, complex worlds. The game will also allow opportunities for players to acquire new skills and tools.
Player can navigate their way through the world by jumping, pushing, grabbing, running to overcome numerous puzzles provided by the game's robust physics engine. Players will also face physics-based enemies ranging from the small such as burning logs, to big "bosses" built around one of six AI "brains" available in the player's toolset. In addition, harmful objects can be placed in the game, such as pits of fire and being "squished" or flattened by an object that cause the player to restart that section of the level; players pop and roll out of restart points nearby.
A scoring system is also in place, in the form of a time trial with a start and end gate and players collecting world items such as sponge. Scoring is based on both time and execution of the level.
All objects and surfaces can have "dangers" applied to them. Any object can be set on fire, electrified, or turned to gas and the character will react differently when it comes into contact with each of them. Fire will singe the character if it is touched briefly but he will die if in contact with it for a longer period, and electrified items will electrocute the player and kill immediately. While gas is also lethal, it is generally a hazard only found at the bottom of bottomless pits. Explosives are also to feature in the game. The player can also be crushed if trapped under or between heavy items.
- This game was rated "Everyone 10 and up" instead of the usual "E for Everyone" rating for LittleBigPlanet titles. However, Sony incorrectly thought that it was rated Everyone and not E10+ and used the wrong rating for LittleBigPlanet PSP's Boxart and information online.
