Fans of the series will enjoy LittleBigPlanet for the handheld with a few changes taken in and out.
The plot for the PSP version takes place just after the first LittleBigPlanet where your Sack character decides to go on Holiday. Where you will be guiding your Sackboy or Sackgirl around various places around the world like Australia, China and LA; unlike the first or second LittleBigPlanet games where you had to save the day, players can just actually chill back and relax.
Gameplay: Anyone new to the series will know that LittleBigPlanet is a 2D puzzle platformer, if you have played 2D platformer games in the past on various consoles. You'll be guiding your Sack character through each level as you progress your way through around the world. As you go through each level you'll collecting prize bubbles which will have a tool item which you can use to make your own levels in LittleBigPlanet.
Not only that you can also pick up stickers which can be used to place anywhere in the game, some puzzles will require you to place a sticker on something to activate a switch to move on. During the first level in each area you play through you'll also get costumes to dress up your sack character. There isn't really much else to say about its gameplay you're using the analog stick to move, and the directional pad to control your sack character's emotions from happy, angry, sad and worried.
Anyone who has played LittleBigPlanet if you pass a checkpoint and you die you ends back from the checkpoint, but instead of having 4 chances through each check point. The PSP version takes away 100 points away from you instead which makes it less-frustrating for players when it comes to certain parts of levels that became tricky to get passed. Downside to the PSP version is that there is no online multiplayer you can play up to 4 players online, you won't be able to do that in the PSP version.
Graphics and Sound: For a game that looked really good on the Playstation 3, the PSP version of LittleBigPlanet does a good job on its graphics, visuals and animations making it feel more like a Playstation 2 game but being ported from the PS3 version. Most of the levels in Story are quite well detail Media Molecule sure know how to make creative levels in the LittleBigPlanet universe. The only thing you may find annoying in the whole game is that there a lot of long loading times which can take forever for a level to load, this affects both UMD and Downloadable version too.
Fans of the series will also notice that Stephen Fry provides more voicing and helping you out in LittleBigPlanet from its opening video to its first three levels through the beginning of the game. Most of the voicing is all random gibberish from various tools that are used for characters that appear in levels which you can also use in your own levels.
Soundtrack also provides a great touch for LittleBigPlanet lovers and newcomers a like who own a PSP, and be able to use them for making your own levels plus there is more DLC stuff you can download from the store.
Overall: As a fan of the LittleBigPlanet series was amazed how well the game was on the handheld, but however it does not support online multiplayer, but you can create your own levels with the tools and materials have collected through the Story. You can also share and upload your own levels local and online which makes it feel solid and close to the Playstation 3 version on its creativity.
However beating the main story can easily take you around 4-5 hours to finish making it feel really short, but plenty of DLC content to pick up from the Playstation Store but may take a while to download from the PSP, unlike the PS3 version which can take under 5 minutes to download.
Fans of the series will get the most out of LittleBigPlanet for the handheld with a few changes taken in and out of the game.
