For Italy, it was Stratagemma (located in Florence, walking distance from the hotel we were staying at -- and very close to the Duomo, apparently). The visit really drove home several things to me:
- the web and its tools make finding such places, and managing your expectations, so much easier than in the past. I was able to find the location via Google Search, got directions to it via Google Maps, and was even able to enjoy online virtual tours of the locale.
- getting new blood into the hobby / hobbies is important for any store (and any hobby). They were having some kind of Pokemon card game introductory tournament when we dropped by, and boy was my son excited! He started chattering animatedly at the boys (roughly his age) who were playing. They politely listened, but perhaps understood as little about what he was saying as my son did about what they were saying. But the enthusiasm was reciprocated until I stepped in to let them continue with their tournament.
- different locales have different preferences. I had no real understanding about what was popular in Italy, much less in this particular corner of it, but I was surprised by some things nevertheless: a Cyberpunk 2020 RPG (reprint) prominently displayed in the window, and apparently a call for players on the bulletin board; the absence of Pathfinder and the dominance of D&D 5th Edition; some local RPGs in Italian, but also some international RPGs in English on the shelves.
I would've loved to stay to discover more about the sub-culture, but museums, sights, and food were calling us to other parts of Italy.
