Before people go getting their hopes up I would like to point out that a 3 Mbps connection is required a 5 Mbps connection is recommended. Other than that, requirements are very low.

Wait, so I can play all these games for free?

Why can't OnLive exist in Canada? :(

" Wait, so I can play all these games for free? "

So I can play a bunch of outdated games I already own/played or had no desire to for free because most of the games are over 2 years old. Great where do I sign up ?

Honestly I wanted to see the list of free games and I was disappointed.  I am glad to find out OnLive is not a scam like The Phantom or Gizmondo.  Good on them but they aren't going to win many customers with older 3rd Party games.  "

What a bunch-a-who-cares

Because that's totally not what Steam is about. "

Steam has sales on current and very popular games. I got a bunch of high profile recent releases heavily discounted during the holiday sale. They also release most PC games at the same time as disc copies, and they often allow you to pre-order and pre-load some of the bigger games. Where as OnLive has VERY few recent games, and even fewer good games. And your also playing them in a really crummy way. Better than nothing, sure, but not better than playing them the way they are meant to be played: without countable lag. "

I can't believe this is going to turn into another onlive sucks thread. I'm not a huge fan myself. I haven't purchased anything, my credit card number isn't in the system, and I don't plan on doing business with them any time soon. However, right now I have 18 games that I can play on my old laptop while propped in bed with a controller. I can make it through couple of games I'm interested but haven't played with really no investment on my part. That's the bottom line for me. I come to Giant Bomb because I like to play games, not to play too-cool-for-school on the forums.

Steam sales almost always have incredibly old games.. "

Kings Bounty being on here is really cool.
 
As for Onlive bashing....what did you expect from this service? Lag-free gaming? It's impossible until the world is able to connect with 10ms or lower...which would require a complete restructuring of our current interwebs.

New games available.

Titan Quest: Gold Edition
Ceville
The Maw
Trine
Madballsin in Babo: Invasion  
 
On week left to play for free.
