Google is actually not a good way to find new gaming stores. Because some of the stores are more like comic shops, so they won’t come up with terms like “Dungeons & Dragons Atlanta” or “Wargaming Atlanta.”
To find stores that sell Dungeons & Dragons stuff, go to the D&D Adventurers Guild website and enter in your ZIP code. You’ll get a list of stores near you.
Paizo’s website has a list of retailers according to the state.
Free RPG Day is also coming up this weekend, on Saturday. Find a store near you.
For wargamers, it’s a bit harder, especially on the historical side of things.
The Army Painter has a store locator.
The Flames of War website also has a store locator.
