the Little Big Planet series was the game of me and my siblings childhoods. My favourite part was the community levels because after you finish the main story, there's no reason to play it all over again. I'm upset that such a huge feature to the previous games isn't there anymore. Customising your sackboy was really fun, and I always had tons of saved costumes. You can still customise your sackboy, although it's really limited with no stickers.
Overall its a great game. If you see the game as completely separate from all the Little Big Planet games, then it can be really fun. If you go into this expecting another Little Big Planet game, it isn't for you.
