Out of curiosity what kind of titles are you interested in these days?
I'd be interested in stuff for OSRIC (e.g., XRP's "Advanced Adventures" line), and I'd also look at Swords & Wizardry and Labyrinth Lord supplements. And I think highly of the material for Astonishing Swordsmen & Sorcerers of Hyperborea.
When I was growing up, my favorite game stores sold the big games of the day, but also had used and out-of-print material, new and used novels, lots of Avalon Hill wargames and other boardgames and miniature wargames, magazine racks that included things like
Heavy Metal and
Strategy & Tactics, miniatures (both for D&D and for various historical wargames), et cetera. I'm not expecting modern game stores to carry that exact mix of stuff, obviously, but it's a point of difference between then and now. That is, when I'd walk in one of those stores, I was interested in almost everything they carried -- or, at least, there was something for me in each section. That's not really true, these days, but if I found a store that had a big used/out-of-print section, and that carried a variety of "OSR" RPG material, and wargames/board-games, and novels, and stuff interesting to historical wargamers...well, I'd frequent that shop!
But like I said, I recognize that my gaming interests are no longer mainstream, so I understand why there are very few shops that seem to cater to my particular set of tastes.
