I am glad that there are a lot of new companies giving it a go but not sure how many will survive long term. Back in the old days, half a dozen manufacturers pumped out a title every couple of months and sold reasonable volumes to mainly operators and arcades. Pins were made back then mainly to make lots of money. These days they are mainly made to collect. I personaly do not have the space or money to buy one or two NIBs every year. All these new starters need to target the younger generations and not just the oler collector. Not sure if their models have considered that important factor. Unless you can hook the younger player, you will not succeed. I started playing pinball in 1967at the age of 8 and kept playing a lot up to 1983 when I focused on my career over pinball. The same hook probably happened to the next generation in the late 80s and 90s, so they were your 2 great pinball eras of the past. The last few years have seen a resurgence due to these 2 generations of players creating man caves and home collections. What next? Anyone's guess.
