OnLive, the streaming video game service, is now free
Games still cost money to buy, but the main thing thing is that you now have access to fully-playable 30 minute demos for free. We were finally able to test the service, and it really is rather good. The client is attractive, smooth, feature-rich -- and playing any game is just a matter of two or three clicks. The video quality really is astoundingly good -- and even though we were warned that latency might make games unplayable in the UK, it certainly felt responsive enough!
As for pricing, games cost the same as they would in the store, or perhaps a few dollars cheaper. Batman: Arkham Asylum is $39.99, while Assassin's Creed II is $29.99. There are also 3- and 5-day passes for $4.99 and $6.99 respectively, however -- and a 5-day pass is probably all you need to finish a game...
OnLive is currently only 'available' (i.e. low-latency) in the US, but it's set to launch in Europe in 2011. How exciting!
