I was at Stranger Things Experience in NYC this weekend. I saw a lot of new people playing the ST pinball they had there on freeplay. Anyone that thinks 4 flipper buttons is a good idea should observe players in the wild. One family started the game and kept pressing the action button on the lockdown bar to activate the flippers. They were getting really frustrated, thought the game was broke. I showed them the flipper buttons on the side. Other people did not know how to start a game. Other people said "aw shucks" and walked away after the first drain not knowing they get more than 1 ball. Now, clearly, these people aren't necessarily the main target audience for all location pinball play, but they are much closer to the target audience than the 0.1% of the audience that wants to do stage flipping. 4 buttons is not just perceived as more difficult because we've all been trained on two. It's inherently more complex cognitively, by a factor of about 4x. Quadruple the complexity. To appeal to 0.1%. Some pins have four buttons. Because something has been done does not mean it's a good design. The world is full of bad design, more bad than good. Anyway, I will cease now. Hot button topic for me as a video game, software, and product designer of 20+ years
