Quoted from pin2d:It is crazy how many acronyms there are on this site! Another question - I think the most important feature so far for me is a large main goal (or wizard mode? Not sure if that is the same...) to shoot for, like the Rule the Universe in AFM, Vacation mode in White Water, Somewhere Over the Rainbow in WOZ, etc...any recommendations on good affordable-ish pins that have modes/goals like that?
I agree that a game with a very tough to achieve wizard mode should be your goal. that's one of the best ways for a pin to stay interesting in a home environment. Basically, 90s DMD games or newer Sterns. Older games are certainly fun -- I would love to get some older games into my collection -- but if you're looking for depth of ruleset in terms of number of modes and things to do, the newer stuff is what you're after.
Another recommendation I have is try to find one that's in very very good mechanical shape. If I were you, I would not jump into the hobby with a "project" pin. That's not to say working on them isn't fun, but it's probably a better idea to get your feet wet on a game that only needs occasional minor maintenance (and they ALL do!!), rather than something in need of immediate board work and rewiring and stuff. never, ever believe someone if they tell you "it probably just needs a fuse..." or similar stories about how easy it will be to fix the broken game they're selling.
So anyway, given those factors, you're probably looking at an investment of at least $2500 for some of the "lesser" DMD titles. Get up to the $4k range and you can start looking at some of the fancier, more coveted games like Twilight Zone, Star Trek: The Next Generation, The Addams Family, etc.
Everyone else is right -- these things do have a tendency to multiply! Welcome to the hobby, though, and welcome to Pinside!
