Nearly every single game that I have ever purchased before 2015 could be considered a "good deal" by today's standards. What is the sense in rehashing it all?
There were more pinball games available than there were people who played them. It's quite simple. No one wanted to mess with a faded Fish Tales back in 2005. No one wanted a non working 4K Monster Bash in 2005. $1,000 Cyclone for sale in 2005? NO ONE WOULD TOUCH IT! EVERY single title pre 1990 in 2005 was priced 200-800. ALL OF THEM. I know because I bought all of them around me.
