Of the many FLGS' I've had the pleasure of patronizing over the years, my absolute favorite was the legendary Sci-Fi City in Orlando, Florida. The place was massive, like one of the smaller Walmarts. Several whole aisles of just RPG books, several whole aisles of just model train supplies, several whole aisles of just 40k, etc., and then a massive play space with tables and terrain and lounge furniture to boot. There were 40k tournaments, Magic drafts, folks playing Shadowrun, CS lan games, and old fogeys playing 6mm Napoleonics not just all at the same store, but often at the same time.
Recently I encountered a store near me that advertised itself with a name similar to "Forgotten Hobbies," implying to me that it had stuff for older, more obscure hobbyists - maybe ham radio, maybe RC, maybe model trains, maybe if I was lucky some RPG books for systems other than The World's Most Marketed Roleplaying Game.
No. They're a Funko Pop dispensary. They sell basically nothing else.
The nearest game or hobby store is 30 miles away. As I get older and consider an early retirement, I am extremely tempted to open a hobby store and make it an actual good FLGS and only worry about not losing too much money.
This is, of course, idle fancy. Looking at the indie scene in RPGs, by the time I hit the place up and running, the big trend would be pure degenerate tranny genital-gazing, GW will have patented the concept of using dice in wargames, and Tamiya will have gone out of business, replaced by 3d printers.
