Haunting Ground a.k.a Demento(in Japan), produced by Capcom, is the lesser known horror game of the Japanese giant, the better known being Resident Evil. Why HG wasn't widely advertised by Capcom? What happened?

It was the year 2005. Resident Evil 4 happened. 'Nuff said.

It's actually surprising, considering the game has high production values, therefore a considerable budget must've been assigned to this project. Why Capcom didn't advertise it as much as RE4 is beyond...
