You guys may, obviously, do whatever you feel like.
BUT...
When I play Harem games, the one thing I don't do is to limit the scope of the Harem. In other words, I don't refuse anyone. Yes, I'm that much of a greedy MF'er (hi there Martha). Never had the chance to regret it yet.
In this particular case, this Dev dared to break with the traditional smoking hot perfect 10's and introduced characters that challenge the boundaries of traditional beauty. All 4 of them have "something" out of the ordinary. To me, if for nothing else, this tickled my curiosity (and with Kim and Debbie something else was tickled) and made me want to learn and play a lot more with them.
You guys know what Extraordinary means, right? Do as you please, maybe you'll never know what you missed
