This is what happens when you have a game company that doesn't know how to properly monetize online.
They could've had a "Capcom Arcade Cabinet" with Bemani, selling full Beatmania mixes along with DDR et others. It's not hard as a lot of DDR and Bemani has already been emulated on M.A.M.E. Just sell each mix separately at $30 and up to $60. They could bundle a DDR pad with a d/l code and Beatmania keyboard with a Bemani code. Of course the people at Konami are too incompetant to realize this.
p.s. $80 million is not that much for MGSV considering how much some of these Western games cost. I feel like saying Hideo should've licensed the CD Projekt RED engine to save money.
