Do you have a kick-ass computer?  Are you going to buy Far Cry 2?  If you pre-order Far Cry 2 direct from Ubisoft, they are going to give you a digital copy of the original Far Cry.

From Ubisoft:

Far Cry 2
Far Cry® 2, the next-generation first-person shooter from Ubisoft, will take you deep into the most beautiful but also most hostile environments in the world: Africa! More than just a visual and technological achievement, Far Cry® 2, the true sequel to the award-winning PC game, will provide you with an unprecedented gaming experience.

Caught between two rival factions in war-torn Africa, you are sent to take out "The Jackal," a mysterious character who has rekindled the conflict between the warlords, jeopardizing thousands of lives. In order to fulfil your mission you will have to play the factions against each other, identify and exploit your their weaknesses, and neutralize their superior numbers and firepower with surprise, subversion, cunning and, of course, brute force.

Far Cry (FREE GAME)
After escorting an inquisitive journalist to a remote tropical island, Jack Carver finds himself stranded in paradise, hunted by an unrelenting team of highly trained mercenaries. As Jack, you'll explore a vast island chain rendered in exquisite detail through state-of-the-art graphic technology. Outwit hordes of cunning mercenaries, snipe with precision from more than a kilometer away, and use every vehicle, weapon, and strategy at your disposal to outlast the island's evils and escape with your life.

If my computer could handle Far Cry 2, I would be jumping all over this.  I only ever owned Far Cry on the Xbox, but Scott and I had some crazy fun with the map creator.  We made one that took over 5 minutes to reach the top of.

Even though I see nothing about it on the site, the image states that this is a short-term offer, so don't dawdle.
