Of course it is a real gambling machine. If it makes them money to have the DMC brand on this kind of thing, then of course they will do it. This game only effects adults anyway, and they should be old enough to know that what they are getting themselves into.If this is a real machine for gambling, then its another proof of capcom having no shame.
As a game designer you should think of how unethical it is to teach kids to gamble.
Gambling is really bad...
