Why are people disappointed or shocked by LocoRoco's sales?
Nintendo, Sony, and Microsoft, at the start of the generation, chose to target their own unique consumer groups. Nintendo wants the young and general audience; Sony wants the mature and "jock gamers"; Microsoft aimed their sights on the hardcore gamers.
Sony creating a game like LocoRoco in the first place is as laughable as Nintendo temporarily acquiring the Resident Evil franchise and Microsoft putting money into this Viva La Coocoo Racha game that's being released by Rare. All three companies had made their bed and now they've got to sleep in it. So when games like LocoRoco, coming from mature-games central Sony, fail sales-wise, I can only chuckle. Just like I chuckled at Nintendo's lame attempts to penetrate the mature audience. Just like I'm going to laugh when Viva La Rasa bombs for Microsoft/Rare.
