Few days ago I was checking what domains about game portals were free to buy, and I noticed that GoogleGames.Com was free. That is weird, how could they forget about that domain? Looks like Google is interested in casual games advertising, but not in developing them, or in building a portal! Will be a hard time for Mochiads or GameJacket. This is a great news for Developers, even because, honestly we are not earning very much with this system right now, but actually the guys from Mountain View are pretty slow, the market is fermenting right now. At the Casual Connect of Seattle Bernie Stolar said: "I'm going to be very clear right now, Google is involved in in-game advertising. I'm going to say it one more time, in case there's any misconceptions here: in-game advertising. This is an area that Google believes will have tremendous growth over the next number of years. ..." "No Gbox, Bernie?" asked Google's Greg Schaffer. Nope, no plans for a console, Stolar said. And no "Google Live," no video-game portal, and no video-game search, he said. Later, Stolar reiterated, "We are not going to be a publisher or a developer or a portal for games, at all. That's the jobs of everybody here. That's why we want to partner with you." That means game publishers will be able to use the Google system to put advertising in their games, and advertisers will be able to work through the Google system to buy ad space within games. They didn't show how the ads will appear but they plan to offer targeted video ads before and after a game, as well as in the middle during breaks such as when a player clears a level, said Eva Woo, a member of the Google games advertising team in a separate briefing for press. We just hope these ads wont be too annoying for users, and possibly that they will pay a lot!

You have made your game, you have tested it, it looks so cool that you are sure to sell it to someone and make good money out of it, but the problem is HOW?.
Well, it is not so complicated, actually if the game is really well made it will take you only a couple of days to monetize it.
First important thing to know is that if you want to sell an Exclusive License is good to NOT publish the game anywhere or a lot of Sponsors wont be happy.

Flash Game License is maybe right now one the most important website for selling Games made with Flash through Bids, but sometime is little bit slow, because you have to wait for the Games Scout to find your game there and bid for it.

If you want to be faster and select your sponsor, you have to contact them by E-mail.

It's very important to write a clear mail specifying in what you are interested,
1)NON-Exclusive: you will be able to sell the license to many sponsors with a lower price.
or
2)Exclusive License: You sell the game to only one sponsor.

Remember to add the SWF and some ScreenShot in the mail, then cross your fingers and wait at least 4 days to compare all the offers.
Good luck!
