Already made this decision, as I (mostly...I can't turn down a good deal) refuse to own more than 1 EM at a time when I can only have 4 games. Crescendo. Bought it for my wife and it really grew on me fast. It's so brutal. It's not deep on features, it's not "nice", or complicated, it's just a pure game of pinball, and one of the few times you'll ever see a bank of drop targets that is not lined up side to side. If you can manage to drop the full bank once on one ball, that's pretty good. If you can do it twice, I'll shake your hand. Three times, I might just grovel at your feet and ask for lessons.
The fact that someone had the balls to put 2 inch flippers on this thing, with no active slings, and 2 pops right near the flippers and outlanes, and then the shots to get back up top are WAY off to the side making them very difficult is genius. Nothing is safe. Good luck trying to shoot back up top through those drops, too.
Always figured I'd be sitting on a game like Atlantis or Kings and Queens....something with a bit more to it, but really....it's just a fast, fun game that's black and white, no BS, and sitting next to three DMDs, it's a perfect fit for me.
