This site will be going away soon, though I may keep a form of it online for a while. Please use GameStoreDB.com from now on.
Why not just use an online yellow pages? Because even though some have a "games" category, this is usually not as specific as the category this page is trying to serve (german games). Second, this page allows users to include comments such as info on their selection of games. Plus, I haven't seen a yellow pages that has the 'enroute' feature this does.
How does it calculate distances? It uses zip codes, and calculates distances as the crow flies, so you may get occasionally misleading results.
Apologies... but it currently doesn't support addresses outside the US, and you can't yet lookup by place name. The former will only happen if someone can supply me with a placename/postal-code to lat/long database for the rest of the world, and the latter will happen when I get around to it.
The database currently contains 449 stores.
For example, enter "02145" or "Boston, MA" (without the quotes). You may use a name for one end of a trip and zipcode for the other. In general, zip codes give more precision than place names.
