The problem with games like this one and many others is they have no pressure release character. Games like this, if they expect to hold people's attention for long term need to put in actual sex with some character early on. The highlight is the mom and all the other milf's, so putting in a token character, like a prostitue to spend your hard stolen money on, would be a good way to give folks what they want, while holding all the things everybody really wants for later, and showcasing the art and animation.
I really dig this game, but it just lacks staying power. Give people a bit of sex with a generic character to wet their appetites for what is to come.
