Dissertation - NFS

To whom it may concern, 

My name is Jerome and I am currently doing my dissertation on Need For Speed.

My topic of dissertation is: "Do the different types of in-game advertising in “Need for Speed” game have the same influence memory retention on gamers?"

Knowing that there are different of advertisment present in this game (Product placement & real world advertising) the aim of my dissertation is to analyse which of these two have a bigger impact on gamers. I have been looking for information on the internet but seems that there is not much around. 

Can someone help me about this topic. I got some results from some test and I had some interesting outcome which can be very interesting for EA Games. I would like to compare my study with people who did the same thing.

Kind regards

J
