Disagree with the negative FGY comments; love that pin! (And that's coming from a guy with 10 B/W titles; not a Stern fanboy by any means.)
Mini Stewie Pinball rocks; definately a challenge (at least for me) to light all its inserts and get "multiball" on both fields.
IMHO, the key to any title not getting stale is simply to add more pins.
Happy flippin' to all.
