Not condoning the mode, but the video has some information wrong.
1) Mondo staring at the women doesn't excite
them. That's to fill up his 'Guts' meter so that he has the courage to make the move, as it were.
2) He doesn't give cash as a present. There is a gold coin (like a collector's or commemorative thing) as one of the gifts, but it's not like he hands over bills in exchange for sex. :/ Gold coin vs. dollar bills is probably just semantics for some, but the video really kind of misrepresents it.
3) My impression from speaking with Suda at dinner after E3 about the mode itself was that it was just a silly break in the action.
Again, not trying to defend it, but I felt the video got a few things wrong. Take it as you will, I guess.
