According to my AdSense ads, I need to play some new game called "Evony."
Those ads are appearing all over non-relevant web pages.
I had the same just with another type of online game, spread over on real estate related websites etc. I wrote a mail to the Adsense team that these were absolutely non-related ads, but it seems they couldn't care less as the ads were running for a few more days. Anyway, if it gives you a headache, just manually block the advertisor.
