I agree. I never cared for University. I'm very happy that I could get the one little object separately rather than just buying a whole expansion pack just for one little item I loved in Sims 2. Of course, there's already threads several pages long complaining about them offering the Cow Plant as a premium item at the Sim Store, as appose to putting in an EP.
Personally, I'd rather spend 500 Simpoints (five regular American dollars I think?) for an item I loved back in Sims 2, than buy a whole expansion pack just for a cow plant. Good thing I only played Sims 2 when I was a house guest.
If you're impatient like me, you can get it for §500 on SimsSocial.
I'm guessing if this item does work like it did in Sims 2, chances are, Metro will ban the Cow plant in the Immortal Dynasty Challenge, since (if I remember correctly), it kept the Sims life span up. I'll of course, let Metro, who did play Sims 2, make the judgement on that.
