Sony's problem isn't with family friendly titles, it's SCEA's ineptitude of selling their games in North America, no matter the target audience, some of their games manage to sell up to three times more in Europe, the only IP they have that can debut at over 1 million on NPD right now is God of War. They relatively killed Gran Turismo in North America, & Naughty Dog's games still sell <1 million in their debut month despite managing to sell 8-10 million units WW. LBP also manages to sell ~4 million despite having weak numbers in NA.
SCEA's marketing team needs a complete overhaul if they want their games to do well in NA. That includes capturing the family market, they will almost certainly fumble with R&C's marketing next year.
SCEE never had those problems even in the early PS3 days.
