As a teen (like 14-17) I played non stop, every night. Once I convinced the parents to get a table, I played for months straight, practicing even if I was just alone. I loved it. Kids eventually got in the way of playing, and I always thought I would have one again one day and use it that much. So when I finished my game room a few years ago the first big accessory was a pool table.. Dropped a few pennies, got a nice table with 3 piece slate (1 1/8" slate) and had it professionally installed. Played about 20 games total in 3 years. Guests played but over time, house parties went from 3 per week to 3 per year, so it got little use. Like everything else, it was a bad attempt to re-live my childhood. Plus after years of not playing, I sucked.
And yet, the new house will have a 13'x22' "Rec Room" which is just begging for the pool table. I will spend stupid money having new felt put on (had to tear it off to move it), having it leveled perfectly, and then it will get used 3 times a year when I have a party. But it will make the room look awesome, lol.
The same went for the mame cab, the electronic dart board, the fire pit, the hot rod car, the hot tub, etc. The only thing that I spent money on over the years as a "luxury toy" that got constant use was the home theater and the shop. Those two are going in the new house, with "dream" budgets only because I know they will get used.
