Prices are crazy but we should probably also be a little bit grateful as it's meant more people are entering the hobby. There was always the worry that "Pinball with die out as people in the hobby get older" but that doesn't appear to be the case. There now seems to be a healthy stream of people in their 30's and 40's buying games, including new games. As others have said we are in a new golden age of pinball.
The only bad thing about the crazy prices is well cost of entering the hobby and buying new games. I'm thankful to own 6 nice games, 5 of which are newer games. However, if it wasn't for entering the hobby 12 - 14 years ago and buying games at way lower prices I probably wouldn't have the games I do today. I've just been trading up to newer games over the years in part due to the profits made on games purchased 5 - 10 years ago.
