My collection is small but despite this I've shopped and torn most of it apart at one time or another. Space Shuttle & Firepower were restored by me. I've taken Whirlwind and Space Station down to bare PFs for thorough cleaning and shopping. I've had Dr. Who's mechs and mini-pf apart at one time or another. Cue Ball Wizard is pending teardown but I've juiced it enough to preview and plan to have my 11yo daughter do most of this, it's pretty easy. All these games have their PITA aspects, but it's all straightforward.
So I have a Big Hurt as a project and holy hell is that thing a major PITA. Gottlieb threw everything they had into this game, and it shows via an incredibly complex playfield with multiple overlayed habitrails, VUKs, scoops, subways, motors, ramps, a 40-pound scoreboard, etc. But that's not enough! Everything is interconnected so there's not a single area that's accessible WITHOUT removing (multiple!) components from at least two more assemblies. Now add infuriating metal acorn nuts that remove the posts with them, AND posts that were hermetically sealed with Loctite before installation! It still comes apart s l o w l y and methodically, but I now see this pile of assemblies and parts from layers, with random peculiarities of pieces used in one spot versus another and... damn, there's gonna be so many ways to screw up reassembly, it's astounding.
Big Hurt was made 20 years ago and I often hear people say games are simpler and less complex in many ways since the glory days. While I'm sure Big Hurt is no Twilight Zone of complexity, it has to rank up there. The recent pin renaissance may have introduced a few games that earn more punches in the tech card than others. And there's gotta be games that make people consider selling rather than dealing with 'em...
...so what ARE the games that should have the warnings "Not for the faint of shop" and/or "Abandon hope all ye who lift the playfield"?
