Nanny Mania is a nice game from Big Fish Games, though I don't find it as challenging as some of the other games I've purchased. I find myself getting through this game fairly quickly, but it can still be a nice diversion.
In this game, you are the nanny taking care of the house and children for the parents of the household. You have to pick up clothes scattered around the house, put them in the washer and dryer and then put them away, take care of the baby's diaper and give baby a bottle when needed, straighten things around the house that the kids mess up, make the beds, etc. The game does not have as much to it as some other Big Fish Games, and you might find yourself getting bored after a short period of time because there is only so much required of you.
I still think it can be fun to play if you are just looking for something to fill up some empty time (which I don't have much of), or if you just want something to play that isn't very taxing. But if you want a challenge, I don't think this game will fit the bill, at least it didn't for me.
