My friend just notified me of something i never really noticed, on many websites, the sidebars have commercials for ddo, that involve broccoli and fighting traffic. He told me, they are really, really annoying, and made him hate ddo before anything else.
This sort of makes sense, i doubt new players come and play ddo because they thought "hey, im fighting traffic and in that game there are dragons", and seeing that constantly as advertising for a game could get sort of irritating.
Personally, i like new players coming into the game, more random PuG material if nothing else, i would suggest getting better ads, maybe short videos of gameplay, or screenshots of the game.
Also, dont make them have auto-sound, it irritates people more than anything else.
