Why are you creating separate date routes ? Up until now Myriam has been effectively dating most of these people anyway, why the sudden decision to have her choose just one? Are these designed to lead her into exclusive long term relationships with all these people, which will form particular endings to the game? Because if not, you could just have her continuing to see all or most of them?
If you choose for her to date one of these people, will that permanently exclude her from future content with some or all of the others? I noticed in the last update, on my playthrough Myriam couldn't contact either Mike or Danny for help, just Dave ( the other two were blanked). I can understand Mike, because I chose for Myriam to have sex with Danny instead, and that leads to another sex scene with him at the cinema. But what choice did I make to exclude Danny, except choosing to reply to Crystal's email first? Is Danny now out of the picture because of that, and other people she could have replied to by email?
Personally, I don't mind waiting till you can create content for all the routes in one go. Either that or doing it piecemeal over several updates, makes no difference to me. Waiting for updates to a game that I like, has never been a problem for me. In the meantime, I have plenty of others to keep me occupied. So whatever works best for you, is perfectly fine for me.
