Just a rumor for now. Also, not exactly "$6" per game, but it's in that range. From CVG:
While Sony has yet to officially announce how much it will cost to rent a streamed PS3 game, the imagery (pictured below) lists Uncharted 3 for $4.99 and Far Cry 3 for $5.99.
Officially, Sony has said the game streaming service will launch during summer 2014 in North America. Unofficially, it has been reported that PS Now won't arrive in Europe until the first quarter of 2015.
For a "low latency, high-quality gaming experience", Sony recommendeds that PS Now users have at least a 5Mbps connection. A PS Now beta is currently ongoing.
Thoughts? Expensive or just right?
