A new Walmart Gamecenter Page offers online game sales, and will soon offer streaming game demos courtesy of Gaikai, the cloud-based gaming startup founded by Dave Perry. VentureBeat spoke with Perry about this development, and learned how it works:

With Gaikai, users can play any game through a web browser, without downloading anything. If the user’s connection speed isn’t fast enough, Gaikai doesn’t make an offer to play the game. That way, users won’t have a bad experience.

“Over the next 12 months, when people see a video game on TV and want to try it out, they can be sure the fastest way will be on Walmart’s website,” Perry said. ”It’s an exciting time and you’ll see more sites around the world doing these stealth launches with us.”

Under the deal with retailers, Gaikai gets paid for the number of minutes a user plays the streamed game. Perry said that Gaikai is in talks with 20 game publishers to enable them to reach Gaikai’s web site distributors. It already has a deal with Electronic Arts to stream its games.
