I never nudge... not sure why. I got into pinball from Epic Pinball on dos and 3D space cadet pinball where nudging is impossible to judge. I didn't really play too much when I was younger, where I grew up there were not very many pins and very few arcades.
My dad nudges a ton when he comes over, I don't really care, that's what the tilt mechs are for. However it is something that seems foreign to me at this point. One day I might but so far I spend more time fixing pins than playing them and at least my last 2, once they were fixed, I craved more fixing challenges and got different machines instead.
P.S. 4 of my machines currently do not really work well.
