If this thread is anything to go by then the ratio of players who start the game and continue with it over weeks and months is very high. That's just my impression from reading the whole thread but I can only think of one or two posters saying they had stopped playing it. Her interest in the game should be your guide imo. If the worst comes to the worst and she hates it then you could probably sell it for a good price seeing as it is supply constrained in many countries. She certainly could use it to get in shape; many of us have.
