The specialist agency has been briefed to recruit advertisers for Colin McRae Rally, Brian Lara International Cricket 2007 and a third, undisclosed, title.
The games will launch on next-generation console formats and PC; Colin McRae Rally will also be available as a mobile phone game.
The games will feature in-game audio, video and billboard advertising. If played in online mode, ads in the games will update with real-time offers.
IGA Worldwide's creative communications consultancy, IGA Hive, will be responsible for creating static ads, interactive product placements and co-promotional activities.
