Sony has attempted to justify its policy in North America where gamers will only get the KillZone 2 demo if they pre-order the game.

MTV Multiplayer received this response from Scott Steinberg, vice president of product marketing at Sony Computer Entertainment America:

Offering a playable demo to motivate preorders speaks to our confidence in the appeal of a game such as Killzone 2. We take this approach when we are convinced that the experience will cement a consumer's interest in purchasing.

Retailers will then merchandise those demos within their stores and online to maximize their visibility. Through this process, consumers are often times able to reserve their copy of the final game, which provides an incentive to purchase and helps seal the deal.

We also offer demos on the PSN, which we have done in the past with great success, and will continue to make that available. Killzone 2, for example, will have a downloadable demo launch in North America the week that the game is launching, for consumers who prefer that option.

And what if you don't pre-order "Killzone 2? but want to try the demo? It's slated for release as a download from the PlayStation Network on PS3 for Thursday, February 26, a day before the game's official release date. That demo will be accessible to all PS3 owners.
