I suppose fps games haven't gotten into product placement as have games like the Sims and sport games. No one really wants to sponsor a game that has violence and graphic content.
A research article by Nelson et al. (2004) discussed that while real brands maintained immersion inside the game world, fake brands might offer a chance for imagination (on the part of developers and players) and could add to the humor and entertainment value of a game.
Previous research has also shown that gamers have a rather general view on product placement. Fairly sophisticated views of how the persuasion attemps work (subliminally or explicitly) and the perceived effectiveness of subtle, realistic, placements over blatant, out-of-context hyped commercialism have been witnessed.
Some future research questions:
- Do real brands allow greater immersion or telepresence over fake brands?
- Are fake brands - if clever spoofs - considered more entertaining than real brands?
- Do spoof ads activate their real brand counterparts?
