Just because games were or were not being played does not mean they are good/bad.. when a title has been around for almost 20 years, people are naturally drawn to titles they haven't played. I've been playing pinball since the 90's, and have owned the older titles and put thousands of plays on them. The newer Sterns? Not so much. I want to play the new stuff and get a feel for it. New games feel good to play, after all they are FRESH!! But not necessarily better.
Hell, I was playing The Rolling Stones while I was there, mainly because I hadn't seen/played one yet. And I essentially played every new title I hadn't played as well as older ones that aren't as popular.
