What is an FLGS?
Friendly Local Game Store. Typically, a shop that sells board/card games, RPGs, comics (aka FLCS). Term of endearment because local stores (Walmart, Target, etc.) don't tend to carry such a selection/variety and online stores tend to be impersonal. Your Friendly Local Game Store is where you can go to talk to friendly employees about games, get recommendations, special orders, new releases, and even typically have game events (Be it things like Magic tournaments/releases, or a really good FLGS, you can just stop in and play one of the demo games - maybe even with the employees on a slow day.
The Hollywood Video sub-store Game Crazy (RIP) did this with video games. I never went into one where the employees didn't feel excited to be there and talk games (and not in a condescending way either). Any in-stock title they had opened, they'd pop it into one of their demo machines and let you play it. Special Ordering was second nature for them and they carried lots of niche product (got my US-Released Hori digital Gamecube controller from them on a fluke one day). I've always wondered if Game Crazy would still be around if Hollywood Video hadn't crashed and burned.
Anywhoo, Imagine larger GameStops with real customer service focused employees, a huge selection of both video games and board/card games, still carrying all the geek culture stuff (but lighter on the Funko Pops, please). Someplace that you could seriously go hang out at for a couple of hours, have fun, and not even *have* to buy something.
I can't even be in most GameStops for more than ten minutes because they're so tiny and crowded, I feel like I'm in everyone's way.
