Is there any kind of evaluation or analysing data on the web that shows how the campaigning worked with in video and online games?

What games had in-game ads for Obama? I didn't hear of any.

I guess I was wrong: Obama's in-game ad bill: $44.5K - News at GameSpot (http://www.gamespot.com/news/6200232.html?sid=6200232)

$44.5 K means 45.500,- right? That's not very much...

No it isn't. I think they were testing a new media effort to see what results they would get.
