In a sea of dark, brooding and violent games, it's always refreshing to see something colourful and bright released. In the first few years of its existence, a pair of PSP games proved that good, original games could exist on the Playstation Portable. The first, Loco Roco, has already received a sequel which was released earlier this year. The second, Patapon, has just received its first sequel. The question is if it can retain its charm and bring something new to the table.
