No, not really - at least not for me (I'm 52yo) I think that the differences between the 4x4 and 5x5 are slight. It's one of those things where "if you can solve a 3x3 you can solve a 4x4 and if you can solve a 3x3 and a 4x4 you can solve a 5x5. The hardest part comes with the edges - there's some weird manuevers you have to do to get the edges right and oddly enough the 5x5 is easier on the edges than the 4x4 because the 5x5 has a center edge for each color and that makes it easier to get matches. It did for me anyway. But once I learned the 4x4, the 5x5 wasn't too hard to pick up.
