I started playing in the 80s at bowling alleys. I was never really good at arcade games and could get much more bang for my quarters playing pins. Also it was more rare to find a "free" arcade game than a pin. So many people would either put their quarter in and not know to push "start" or they would match at the end of their game and walk away not knowing they got a free game. After I ran out of money, I could still spend hours at the arcade finding pinball machines to play for "free".
Fast forward 30 years and I picked up my first pin WD?- which I loved because of the variety of each game. Life and family happens and it would be another 10 years before I had the time/finances to afford more. It's a great time for the hobby right now!
