Okay, I found two MySims creepypastas:

The first is Mysims Prologue. It's about how you were sent by Mayor Rosalyn to kill Buddy, who turned out to be Cassandra, and then after that, Buddy was cloned as a dude. Yes, it's confusing.

The other is about some thing someone saw while playing MS Party. I didn't catch all of the details.

There's also a creepypasta about PaRappa the Rapper called PaRappa the Rapper Stage 7. There was nothing on the page, though.
