I heard radio ads here in Cincinnati. It was awhile ago, and it was for a couple different products they have.... I think the sim baseball and Hardball dynasty. It was on the local sports radio station. As some of you may know, the original developer was from the Cincinnati area... perhaps that is why they did it here.
I'm not really sure if this game is a goldmine. I have a lot of friends that I have talked to about the game (many who play fantasy football, etc) and I think a lot of people just think it sounds too involved or not their thing. When you can play fantasy sports for free, I think a lot of folks just don't see the point is paying for something.
That said, I think there are probably still a few thousand folks out there that would really enjoy the game if they heard about it. I'd be curious to know their demographic... obviously male - but not sure what ages.... probably 25-54 would capture 75% of the users.
