I'll be traveling to San Diego next month and, being a WW2 tactical grognard I'll be shopping around for some games.
I'm considering Fighting Formations, Conflict of Heroes, Band of Brothers, Lock n Load etc..
Any good shop in that area?
As has been suggested in a few previous threads on the subject, I recommend Game Towne in Old Town, San Diego.
When I was there last, they had a lot of older war games—almost like an archive—because those games tend to sell slowly. Whether they'll have the more recently-published games you mention in stock is hard to say, but you can call them at (619) 291-1666 ahead of time to check.
Every time I went to the store, I found something new to consider purchasing. It's worth a lengthy visit.
