During the last month I have been testing a few games that allow mainstream companies to buy advertising space inside the games.
One of the game I have tested is
http://project-torque.aeriagames.com
Is a online real-time street race game.
Its still in closed Beta, so there are no real banners on the site yet. But you can see the banners here

The games are free and that attract a lot of people.
But do you think you can make money advertising a website there? Or is it only profitable if you already have a known "brand" like Cola, Burger-King or Nokia?
If you run a website on those banners, chances are they cant remember the URL when they stop playing.
