Moving this to the right section, while I'm here, as it really doesn't belong in Introductions.
Now, I don't know what mod you had in your game before, but it wasn't Insimenator. The Insimenator was never made for Sims 3 and, when it was asked here a few months before the new game was released if it would be, it was stated several times that the Insim would not be made for Sims 3.
It was pointed out in another thread here (
this one, to be specific) that a new mod has been made for Sims 3, called The
SuperComputer. I haven't delved into it deeply to see all of what it does, but according to Mr.NiceGuy it does a lot of what the Insim and the SimBlender do for TS2.
