Though there have been brief periods in the last 25 years when no companies made new pinball machines, for more than a decade now, America's Stern Pinball, Inc. has kept the ball rolling -- and in good form, too!
I like playing Stern's machines, because of three reasons. Most Stern pinball machines are co-branded with a movie or music franchise, so the player gets the feeling s/he is not "just" playing pinball, but is part of something bigger. (I like this for the playing experience, but also because it is a good way to draw in younger players, who may not otherwise be attracted to playing pinball machines.)
Secondly, Stern regularly releases new pinball games. One need not feel "stuck" with the "same old" pinball experience. If you are looking for a machine themed after the movie Avatar, Stern has it. If you are looking for a rock-band themed pinball game, they offer multiples of those, too. Most of all, Stern keeps releasing new models -- a few every year, so new machines featuring big movies and big bands are always on the horizon. Am I sounding redundant? Okay, time to move to the next point, here. ;-)
Thirdly, Stern's pinball machines are fun to play! I always have fun playing a Stern machine. The company uses so many play features you just cannot get bored. If you like multi-ball and tri-level playing surfaces, then you know what I am talking about here! (And you probably already know the great fun of Stern pinball machines. In fact, I am surprised you have not bought a pinball machine already!)
