LittleBigPlanet PS Vita is a puzzle-platform video game developed by Double Eleven, Tarsier Studios, and XDev Studio Europe for the PlayStation Vita handheld console. It is the fourth game in the LittleBigPlanet franchise, a series of puzzle-platformers centered on user-generated content. The game was announced in January 2011 alongside the reveal of the PlayStation Vita, then known as the Next Generation Portable (NGP). The first details were revealed on 6 June 2011 at the Electronic Entertainment Expo. It was released on 19 September 2012 in Europe, 20 September 2012 in Japan and Australia, and 25 September 2012 in North America. The online servers were permanently shut down in March 2021 after suffering attacks during the previous year.

Gameplay: As in previous titles in the LittleBigPlanet series, players control a character named Sackboy through a variety of worlds, utilizing the character's abilities such as jumping and grabbing objects. The game also features non-platforming mini-games and numerous multiplayer options. In addition to up to four-player online competitive or cooperative play, the PlayStation Vita's multi-touch display can be used by two players for competitive games. Pass'n'Play is also available, enabling turn-based gameplay. The Vita's rear touch panel is used for pushing objects toward the player and creating platforms out of parts of the world. Content creation: Players can create their own levels and share them online via the PlayStation Network. The PlayStation Vita's touch-screen display can be used to draw objects and platforms directly in the game world. In addition to these unique creation tools, the game includes all tools available in LittleBigPlanet 2 (with the exception of DLC tools such as the Wormhole). However, materials and stickers/decorations from prior games are not available. Costumes purchased from the PlayStation Network to customise the player's character are transferable between the PlayStation 3 and PlayStation Vita versions, including LittleBigPlanet Karting, though costumes from the PSP game are not available in LittleBigPlanet PS Vita. Content can also be shared over both Wi-Fi and 3G networks.

Additional content: The PlayStation Vita version includes tools from previous LittleBigPlanet games adapted for the Vita's control system, as well as new tools such as the Motion Recorder, Touch Sensor, Touch Tweaker, Touch Cursor, Touch Material and Layer Tool, all of which provide touch-based controls. There are also tools for other purposes, such as the Dephysicalise Tool, the Sticker Scrubber and a tool that creates a jelly-like substance that Sackboy can pass through. Another new tool, the Memoriser, can store data between levels and play sessions. Those who pre-ordered the game received a bonus BioShock costume pack. The pack includes Big Daddy and Little Sister costumes. A "Knights of Old" pack was also announced, offering knight, dragon, and princess costumes.

Plot: The story follows a puppeteer believed to control wooden puppets called the Hollows, dangerous enemies of Carnivalia. He created them as replacements for the puppets he had discarded after being booed at a circus. To stop the threat, Sackboy travels through locations such as the Land of Odd, meeting characters who help him reach the Spooky Mansion, where the puppeteer lives. At the mansion, a tape reveals the puppeteer's name is Franklin, and he has been captured by his own Hollows. After Sackboy frees him, Franklin explains the Hollows were unwanted creations from an attempt to recreate his puppet friends — the Creator Curators Sackboy had encountered on the way to the mansion. Bitter from always being behind the scenes, Franklin had thrown them away; when he later sought them, a tear he shed brought them fully to life. Franklin is ecstatic to reunite with his now-living friends, and when they laugh, the Hollows revert to their original Sackboy forms. Reception: LittleBigPlanet PS Vita received positive reviews, garnering aggregate scores of 88/100 on Metacritic and 88.68% on GameRankings. Justin Calvert of GameSpot called the game the best in the series so far and stated, "This is the game that your Vita has been waiting for. For months, the shiny handheld has been aching to show you what it's really capable of, and with the arrival of Little Big Planet PS Vita, it finally has an opportunity to do so." Calvert, who gave the game an 8.5 out of 10, praised the "wonderfully varied" story levels, "excellent" controls, and the "easier than ever" creation tools, but criticized the tutorials for feeling incomplete. Matt Helgeson of Game Informer wrote, "While LittleBigPlanet has clearly settled into a comfortable groove, it’s still one of the best pure platformers on the market. LittleBigPlanet PS Vita is another stellar entry on Sackboy’s impressive resume." Helgeson awarded the game an 8.75/10 and praised the overall design, graphics, soundtrack, and the developers' ability to create a LittleBigPlanet game on par with the main games. In his review, IGN's Greg Miller concluded, "LittleBigPlanet PS Vita is the definitive LittleBigPlanet game. It's everything you loved (or possibly didn't) from the past games boiled down into a package you can play anywhere at any time." You can collect prize bubbles while watching TV, download user-created levels at home and then play them on a plane, and sink hours into learning Create mode via 10-minute chunks at the laundromat. There are also new features like touch controls, games that don't involve Sackboy, and creation tools that could give you an endless supply of free games. Yes, the jumping is still floaty, the creation tools are complicated, and the load times are a bit too long, but that doesn't stop LittleBigPlanet PS Vita from being an amazing experience. Sophia Tong of GamesRadar commended the narration by Stephen Fry, the controls, and the story levels, saying, "LittleBigPlanet PS Vita encapsulates what the system can do and deserves a spot in your Vita library."
