The PlayStation Network Delivery service goes live across Europe today, offering over 800 movies to rent or buy to PS3 and PSP owners.

Films ready to be downloaded at launch include Star Trek, Watchmen, Bruno, Angels and Demons and Transformers: Revenge of the Fallen.

Rentals will cost from £2.49, giving a user 14 days to watch the movie, but only 48 hours to finish the film once play has started. Buying a movie will cost from £6.99, allowing the movie to be used on up to five PS3 or PSP consoles, though not simultaneously on each. Movies cannot be transferred to a PC for viewing due to piracy restrictions. And movies cannot be transferred to an Xbox 360, for obvious reasons.

1080p high-def movies are also available to rent or buy, for a small bump-up in price.

As a limited launch offer, new PSN users will receive a free copy of the first Transformers, while returning PSN customers who buy Angels and Demons will receive a complimentary copy of The Da Vinci Code.

Sony are aiming to have as many as 50 new title available each week, so if your favourite flicks aren't up on the PSN yet, check back soon and you might be pleasantly surprised.

Microsoft's premium Xbox Live Gold service will be available for free for 5 days in European regions next week, giving all Silver account members a taste of the numerous new additions to Microsoft's online catalogue.

Those taking part in the free trial will be able to do everything that Gold subscribers currently enjoy; online gaming, free demos and premium downloads, and also access to the brand new Twitter, Netflix and Last. FM tabs.

European Xbox 360 owners can access the free trial between 5pm GMT on the 25th November until 5pm GMT on the 30th November.

The rest of the world can connect for free a little earlier, between 12am EST on the November 20th and 12pm EST on the 23rd November.

Sony have confirmed that the next PlayStation 3 firmware update (v3.10) will feature Facebook support. The news comes hot on the heels of Facebook's integration with the Xbox 360, which went live today.

According to the PlayStation blog, "By linking your PlayStation Network account to your Facebook account, you will have the option for the PS3 to automatically update your Facebook News Feed with Trophy and PlayStation Store activity".

It continues, "This update also enables developers to set specific criteria in their titles to publish additional game information to your News Feed. You can then check out your updates, and those of your friends, on Facebook, Twitter, and other social media favourites through the PS3's built-in web browser".

Though users cannot update statuses and post on Facebook walls as yet with the update, these early moves at social-network integration hint at big things to come from Sony.

Other features set to be included in v3.10 include a revamped Photo category on the Xross Media Bar and an improved friends list.

The firmware update will be made available on November 19th.

OnLive's cloud gaming service looks set to work on mobile phones as well as PCs and laptops, according to CEO Steve Perlman.

At a financial conference in New York, Perlman showed the service running not only on a TV and PC, but also simultaneously on two iPhones.

OnLive works in a similar way to cloud computing. Users choose and sync with a game from an online database, which is then rendered remotely by a ridiculously powerful machine. Gamers then remotely control the game, with the server sending back only the video of what is being played. Therefore a user's hardware can be relatively weak and still be used for high quality gaming, provided they have a fast and stable internet connection.

Perlman did admit that playing high-end PC games on a mobile handset may be too ambitious for the foreseeable future however, but was keen to promote the social elements of OnLive that would be available to mobile phone users.

"We have further development to do, and we need approvals from some cell phone makers before we can release OnLive to the public. So, for now, OnLive on a cell phone is only a technology demo."

A demo it may be for the time being, but it's certainly interesting to see OnLive stretching its legs out in the handheld and mobile market. Here's hoping, hey?

You know you've really won over the hearts and minds of a nation when you get to star in your own web game. Either that or someone hates you that much to spend sleepless nights developing one that rips what's left of your flailing credibility to shreds.

Enter "Grimes Against Humanity", starring X-Factor hate magnets John and Edward.

Players must bounce "Jedward" to the top of the voting tables in a bid to win over the cruel destroyer of pop-worlds, Overlord Cowell (inexplicably portrayed by the Mousebreaker-developed game as German).
