I'm pretty sure most peeps here have seen the ads for Evony Online. The link below will show an article showing the power of marketing/advertising.
I'm not hawking Evony, but you've gotta admit, they know how to lay a 'booby' trap.
DF might want to consider similar advertising to bring new life into the Valve #2 server.
