I have said that DMD will never die cause the fans won't let it! There is plenty of potential for spin-offs.
DoMD: Dreaming of my Daughter in which the characters have "what if" dreams of being with Dee
DoMD: Dreaming of my Dog in which she dreams she is a world of furries and Rocky her man-Dog rescues her from a kennel
DoMD: Dreaming of MY Dad in which Dee dreams of how her father and mother dated in a flashback sequence
DMD: Divorcing my Daughter in which it is legally found out that they cannot legally marry in their country but can if they move out. Meanwhile Rachel uses this time to steal Dee away and demand that her and Dee marry father in a polygamous marriage.
DMF: Dating my Friends in which Elena, Jennifer, and Georgina search for a replacement man as well endowed as Dee's father
These are some of the ideas that posted to Mr. DotGames suscribestar page and I think they might try some of these ideas out.
