I'm on the younger side (27) but the more I play I like older and older games..
Yes new sterns are great and flashy but they "flow" too well sometimes.
Grand Prix has been my go to game lately because Gotleib's Atlantis left and I am horrible at both of them. When you make your shots and the reels flies it is so much more satisfying then looking at a dmd for a jackpot call out and animation.
I get that they don't look as flashy and if the themes are no longer relevant but the shots are harder and more satisfying and good lord if you want to practice accuracy and nudging you can not beat a well set up em.
