Yeah, I'm guessing they meant games that are actually available on the iPad - most of those aren't.
The latest Sims isn't bad, the older ones are week.
Don't know the age/gender of the OP. My 15 yr old girl loves the PC-based Sims, and thus is bored with the new Sims FreePlay game on the iPad already.
