I think Evony should keep the sexy ads for sexsites or that kinda stuff, advert with medieval crap on medieval/gaming sites and also take the chance to get some child adverts for the less mature.
That way you can get the best of all worlds.
imagine you're taking care of business on some site and then an ad with a sexy chick comes on that says: "you done yet? take 5 and play this game a while"
Maybe if they took the time to map out their advert campaign they could get better results
personally, i have nothing against the sexual ads because i'm not offended by that kinda stuff, but i do think they could tone it down a bit with the wrong crowds
