The streaming service, Playstation Now, was launched earlier this year and it lets you play a selection of PlayStation 3 games for either a monthly fee or by renting individual games. The service has been met some criticism because of fairly high prices, and costs $19.99 / £12.99 (the UK is the only market where the service has been launched in Europe) per month.
Now Sony of America has announced a 12 month subscription for $99,99. The campaign is said to be temporary, and is more than 55% off the regular monthly subscription price. Nothing similar has been announced for UK thus far.
