Quoted from swampfire:
Not picking on you , but I still don't get why people say this. IM has 2 ramps, 3 spinners, 2 magnets, 1 kicker, motorized monger bash toy, 3 pops and a ton of stationary targets. Maybe the reason IM is such a great game is that they stopped there.
As time went on, people realized IM's gameplay is really great and fun! However if you just look at it, it's relatively static. The toys are off the shelf Hasbro. No scoops, saucers, VUKs...nothing "innovative" or "different" like we had seen on previous Stern games such as FGY (mini-pinball), WOF (wheel, inline drops revealing a ramp, interesting flipper area), BDK (crane bash toy), CSI (unique layout, skull lock). It was also a reworked Austin Powers playfield. The rules are very very simplistic. So, from a development and BOM standpoint, it's "cheap" ...but fun is fun, so if you're having fun, who cares? The "fun theory" eventually made Ironman a desirable game.
