Shrapnel is very good at getting the word out about updates and new games. The word was out, they got it, but they just don't care about the games Shrapnel offers.
Hell I will pay for an add and run it in the local computer magazine if it will help sell SE IV! Crap its not that expensive up here... But nationaly, in one magazine like PC gamer, well that is about $1200.00 per one half page color add. (Could be wrong, but that would be logical rate. Easy enought to check too.)
You run an add that is a half page that lists your top selling games. Just get the word out, let the web site and the forums do the rest. (The Demos to.)
