Why do people call Ratchet and Clank kiddy?
Because you play as a animal?
And you say last year you got Resistance 2 you know Isonamic made that and Ratchet and Clank.
A game is mature because it has blood or human characters?
Anyways...
Infamous made by Sucker Punch a kiddy developer Sly Cooper trilogy and Rocket Robot On Wheels on N64.
Uncharted Naughty Dog is also a kiddy developer Crash Bandicoot PS1 trilogy and Jax & Daxter PS2 Trilogy.
All of Sony's top developers are kiddy developers so yes Sony is hardcore kiddy.
