While everyone is voicing there thoughts about who is the best route, keep this in mind. Ptolemy is actually being very smart about how he is laying this out. He isn't just doing one route and that's it, like the current Route of say Dating my Daughter, which is strictly a romance route (atleast from what I have seen). He is giving a few different routes to satisfy almost everyones desires all at once, and almost without them even seeing it. Theres a dominant route with Andrea, which I agree is actually my favourite, there is the Sub route, which while not my favorite still has its hot points. (I'm a sucker for a nice creampie, especially when they like it), and then theres the group sex option which is still expanding. Me personally, I don't like sharing Dana, she is going to be mine forever. Romantically, mind you. Roses over handcuffs for me, although they can be handy as well, if you know what I mean. Of course you do, this is a porn game forum, silly me.
Although Mila? I can't wait for her route to be fleshed out, maybe get a route of her own. I don't know if Ptolemy is doing that or not, as I don't know if he has an idea of what he is doing with the game as public knowledge.
But yeah that's my thoughts. Great game so far, love what he has done with it, can't wait for the next version
