Bottom line is profitability - especially earnings per square foot.
Pinball machines are a big investment and they take up a fair number of square feet. That's OK as long as they pull in a lot of coins, but most locations aren't seeing the coin drop.
Maintenance is an issue. Broken games don't earn money and too much labor spent on maintenance cuts into returns. Reading Eddie's log from Modern Pinball shows how much effort it takes to keep these games running and earning. As we've read from others, it seems unless the location operator is a pinhead, they eventually get sick of the maintenance costs and the "out of order" signs and replace the pin with something more reliable.
Then there is the issue where people have seen machines sitting there and no one one is playing them:
-We have novices who look at the modern games with deep rules sets, scratch their head, play it once, and too often it leaves them confused and frustrated. They aren't going to keep pumping in coins trying to learn it.
-Meanwhile too many of our own community won't play pinball on location because they can play in homes or they don't like location machines.
If there is to be a future for pinball, we should look at what those other games are doing to get put in there instead. At a minimum, they are more reliable and are more approachable for novice players. Maybe they also have features and themes that attract a wider audience.
But it would also help if we got out there and supported pinball on location. Guys - if we won't play them, why should anyone else?
