I don’t have FG, but I own Shrek. It’s one of our favorites. Same layout design, different art package and theme. We love the design. The shots and flow are pretty good, especially hitting the right orbit to the upper flipper shot under the upper playfield, the far upper left stand up that drops the metal ramp guard, and the main left ramp. The mini pinball game is silly to some, but we like it. The reason we like it is, it’s essential to achieving one of the main modes - Stewie multiball (Donkey mb on ours). I think the variety of shots is good, and if you like FG and that humor, all the better.
I would trade a DH for a nice FG. We have a few different pins and we play Shrek a lot. It’s a decent pin.
