I am also seeing the State Farm ads, and while they do bother me a bit, there is something else that I noticed that really irks me.

It looks to me like the loading progress bar slows down to wait for the ad to finish playing. I spent plenty of time with Fury before the ads showed up and Zone levels would load super fast because of the lack of textures. Now, with the ads, the loading bar zips across the screen but then slows down just in time to allow the ad to finish.

If I am right about this, it would mean that the ads are artificially increasing the load times on certain levels (Zone especially). While it's a small amount, it is certainly a disturbing trend.

Pay close attention to the loading progress bar next time the ad pops up.
