Is Pinball even your number one hobby?
I've had German shepherd dogs for the last 20 years that have been the very best things in my life. I have two now (ages 1 and 11) that are more fun to play with than anything else.
I have 15 pinball machines and 2 linked Cruis'n Exotica video games. The 12 pins that fit in my gameroom are my personal favorites. Adding a new game would mean bumping one of them.
I have 9 electric guitars, bass guitar, three Fender amps, and assorted keyboard synthesizer and recording gear that I use to play and record my own jazz-rock instrumental compositions.
I have an 80" flatscreen TV with surround sound system wired through the walls and a collection of over 1500 movies (and growing) in various video formats (from BR to DVD to VHS).
(Several lesser hobbies omitted here to save time and space.)
My wife is aggravated by my need to collect everything. If cars are my number one hobby (after the dogs, and certainly my most expensive hobby), maybe I should sell my BBB and MB and my 1964 pre-CBS Fender Stratocaster in order to afford another modern muscle car a couple years from now? I'd still have 13 pins and 8 electric guitars left, just not the best ones.
