They actually are starting to carry a small number of wargames. They have games from APL, DVG, GMT and Compass. However, not many of them. For instance, they have about a half dozen GMT titles. One copy of each. The same with each of the companies. And they are spread out throughout the store, not all in one wargames section. For a niche market, it seems you'd want to make it easy to find.
Currently, the 3 APL games I've seen on the shelf are:
Soldier Emperor
Sea of Iron
and...
Korean War: Counter Attack (now Jay will never shut up.
)
They had a copy of Kokoda Campaign there for a number of months. I guess it finally sold.
