Mary, I own all of the VV's and have only played the first two
on this computer, but have had no problems. I do know if all of your people are around the same age, they could all die at
the same time though. I purchased one from IWin and got one from LDW, the rest came from Big Fish Games I think.

I purchased Plant Tycoon thru Big Fish Games several years ago and it played fine on several different computers. Then I got this new dell desktop and the game played fine for a while, then all of a sudden I couldn't play any more. Barbara tried everything she could think of to help me and nothing worked, then about three or four months ago, I reformatted my computer and a couple of weeks ago, I decided to try Plant Tycoon again, and it played perfectly.
