They both gave the game a 9 and a 90% respectively. Here’s a snip from the EG review:
“In short, the “Play” aspect of LBP PSP is just as good as it is in the PS3 version. In fact it’s better in some regards thanks to the tweaked controls, reduction in the number of planes and more lenient checkpoint system. Most importantly, the environments you get to play through are just as beautiful, the puzzles just as ingenious and the difficulty level just as challenging.”
