So getting in a ton of play this weekend at the local Pin museum games from all generations, it's clear lot of older games, and even stuff in early 90s didn't have ball save periods often. So when did this start, first game to offer it, and when did it become kind of a norm in the industry?
It really showed how frustrating pinball could be especially with games that were not tuned well. There was some machines with clear maintenance issues or tweaks needed, where balls would for clear reasons be going SDTM during ball launches and make for quick games cause no ball saves. Some new stuff has clearly very generous save times, like anything Elwin makes.
