Voila pour toi:
"Sony announced that players who download games from PlayStation's online shop can use them on up to five PS3 machines. If a player logs into his PlayStation 3 account on a friend's system, he can download any game he has already purchased. "You can send that content to four other friends for that initial investment," said Tretton. "We want to get the game in as many hands as possible. It's not about generating profits at each and every interaction with the consumer," he said. "I think that really offsets the argument that says, 'Wow, that's a really pricey system.'""
