It's not a bad game. With the moving furnace/boiler door, Freddy shooting balls, diverter, claw flipper, claw save, etc., it does have more going on mechanically than many games in the price range. The downside (for home use) is linear game progression, but there are some side modes to discover as well. Many guests find it to be the best of my machines on initial plays as it's fairly easy, and with all the giveaway multiballs, it caters a bit to new players. The linear rules being a benefit in that case as a new player can actually see their progress easily.
That said, it will get old fast at home, though Hazoff is right about games like SS and TOTAN getting old fast as well (yet I'd still consider those better games than NOES).
