I have a couple machines at an arcade, and I'll tell you, 95% of my money comes from non-pinheads... and 99% of all the complaints come from pinheads... and a good player will put in $1 and play for 30+ minutes, an average person will be out in <5 mins (games are set to 5 balls) I have nothing against pinheads obviously, I am friends with most of them, but I am not surprised that locations really don't care what collectors think/want because they don't go put money in the machines anyway!
they require constant maintenance, cleaning, and have terrible ROI... I have had a Tron on location since I got it NIB and it still hasn't paid itself off... and that's one of my good earners!
I will say though title is everything, the ONLY machine I own that has paid for itself is my South Park, it's simple, it curses, and you can kill kenny over and over again (which is what most people did)
so to sum it up simply, you want more location games, GO PLAY LOCATION GAMES
