EMs are super fun! You just need to learn how to appreciate them. I didn't at one point either.
I'm 37, didn't grow up with them, I didn't even play pinball as a kid. So no nostalgia. I like modern games, I play my METLE more than anything else right now, so fast and deep is cool with me.
And yet my Abra Ca Dabra and Sky Jump are awesome. And sometimes they hit the spot in a way that a Stern or Williams/Bally game doesn't. They are more mellow, but that doesn't mean they're easy. And you know, when I'm at a show I don't really dig playing them that much either. It's not the right environment for me maybe.
I think if you find a nicely set up 70s wedgehead with some good rules, challenging shots, and a lot of drop targets and you really try and play it to get a good score and pay attention to the game you might find a new appreciation.
They're also really beautiful to look at, so much more style than modern games. I LED all my solid states, but keeping my EMs incandescent is a great reminder of how nice a glowing filament can look. I do use some LEDs in hidden spots sometimes to enhance a color, but only in subtle ways.
