Disclaimer - I have not completed the final world and last boss. I had to put the game down while on vacation, but I have not picked it back up yet. That being said, I have played enough to rate the game with certainty.
I have always been enamored with LittleBigPlanet's design, music choices, and world in general. But for a platformer (whether 2D or 3D) the controls have always been too mushy. I don't know a better word for it, but it feels like your inputs are controlling puppet strings that move the sackboy, rather than sackboy itself. Credit to this game because the mushiness is not as strong, especially when running along the ground. It still exists with other movement features like jumping, fluttering, rolling, attacking, etc. Unfortunately, character feel is a huge factor in how much I enjoy a game, especially a platformer.
The items and gimmicks in the game are all interesting, and the story unfolds in a way which brings them all together in a distorted way as you progress through the final world. The level design and flow of the game are well done. The original music is on par with past entries. The game also uses pop songs from various eras, which I assume were on Sony's label, and has levels that are designed around the beat and theme of the music or artist. These levels really stand out, and I expect you will recognize most, if not all, of the songs used. The visuals in the game are also lovely and diverse. Each world differs greatly in setting from the others, and the colors utilized pop. The visual style is still the crafted world approach of other LBP games, but there seems to be a bit more fantasy/sci-fi influence than I remember. The main villain is both whimsical and eerie, I feel this is one of the best designed antagonists visually that I have encountered. I will have to wait and see if any more depth comes to the character after completing the story, but as of now it is your typical children's story affair. Voice acting is generally humorous and well done, most accents are British which I assume is a result of the studio's location. One other stand out for me were the Knitted Knight Trials. You unlock these by finding a hidden collectable in levels marked with a cube, and they are speedrun based levels that incorporate the main hazard of the level or world in which you found the collectable. These were quite addicting for me.
For those of you who have played games in this series I assume you will know what I am trying to describe when I talk about mushy controls. If so and
A) You don't mind them - Play this game! Those were literally the only downside I can think of in my review. I just hate when a character feels off so much that it brought this game down an entire star.
B) It does bother you - I would avoid the game. Just play Mario 3D world on the wii u or switch if you have it. If not, I am sure someone on this site can recommend a game that is similar on sony consoles. Do note that this game's mushiness is not as bad, so I find myself prone to binge sessions. If I play for 5-10 minutes it is just long enough for me to get mad at the controls. If I power through to around 30 minutes, I can get used to it, and the game's wonderful level design and extra collectables hidden throughout cause me to play 2-3 hours at a time.
If you have never played games in the LBP series I would recommend playing the game. If you like this genre, I can recommend it at its current price. If not, then wait for a sale or for used copy prices to come down a bit. You may not be bothered by the way the sackboy controls, and the game is not a rip-off for the amount of content included. If nothing else, you now have a game that has local multiplayer for 4 people.
3.5 Stars
Update: Finished the final world and boss, had no desire to continue through "post game content". I could see myself returning for this after an extended break or with friends.
