Because whereas LocoRoco's effortless charm and stylistic verve compensated for an occasionally lightweight game design, in Patapon, a similar visual panache and lively effervescence compensates for an occasionally over-complex game design. So, to reiterate: while Patapon has got the same quirky sense of style and visual charm as its predecessor, it doesn't offer the same easy breezy gameplay. Instead, it offers an imposing amount of depth and a considerable amount of micromanagement. Which isn't necessarily a criticism - it's just that forewarned is forearmed, and if you're nuts about LocoRoco there's no guarantee that you'll go bonkers for Patapon, because it's complicated, and it can be frustrating. But then it can also be rewarding and yes, it's absolutely charming and that counts for a lot.
