I have read so much negative forums here and others that pets is a problem riddled program. It does not seem to have all the bugs worked out. think it was released before it was properly checked. EA said the hell with it and shipped. A lot of people have complained.
As for "Seasons" IT ROCKS!!
There is so much more to play with. I got it and love it. I am sleep deprived playing it!!! It was worth the cash
The next expansion looks cool too. Vacation time!!! yeah buddy I will sit back and wait a month or tow after its release and see how people like it and how many problems there are before I buy!!!>.....
