With all history, nostalgia, build quality, etc aside.
Speaking from a players stand point, I think Stern has succeeded.
They play different that is for sure. The games are faster, harder, and in some cases have deeper rule sets. I've probably finished the complete rule set on most of the top golden era pins but I can't say that for MET, AC/DC, LOTR, TWD, GB and numerous others. It's a different era of pinball love it or hate it.
I'm really liking the new games that are coming out and they've done a great job keeping them addictive so that you want to play over and over...
WMS/Bally games will always be classics and hold a special place in everyone's heart but the new era of games are awesome if you ask me. Pinball reborn!!
